I'd say Chrysalis is better overall, more fun; if you're treating them along the lines of how they're portrayed in canon, as villains, Chrysalis is the one whose goals are more flexible in context while remaining the same (conquering Equestria). Furthermore, Chrysalis, unlike Tirek, can better facilitate a state of affairs where the focus is in exploring how she affects the world. You can treat that which happens in her wake as a corrupting influence, as is what happened to Fluttershy in her alternate timeline, out of the desperate circumstances, have an internal struggle, and she can plausibly fail due to her character flaws, with tension therein lying in if it's enough to result in her downfall, or if she tires of it and gets too relentless, drops the games.
Tirek, on the other hand, while he's cool and all, and fun, he has the traits of being relentlessly pragmatic in large part, not too inclined to underestimate opponents, is light on gloating, and unlike Chrysalis, his MO, left unchecked, will *sooner* rather than later lead to an *absolute* victory, where he's pretty much a god. He's more of an unstoppable force of nature when he gets going, with the only things that can really stop him being overwhelming power or being blindsided. You more or less are *very* hardpressed to do a resistance plotline with Tirek and have it make some amount of sense compared to one with Chrysalis.
It also doesn't do Tirek many favors that his fear factor is by and large inversely proportional to how much power he has, as seen by how he in his first form generally has that creepy charisma about him in both S4 and S8, but as he grows stronger, he trades that for the generally less compelling menace ala "unstoppable force" factor. Chrysalis doesn't *have* this problem when she's powerful, due to her gleefully exploiting her [inequine](/images/1279811) flexibility and sadism. She also has a sense of style that is a joy, and has a more visually appealing design... and sadistic villains are fun to me; she quite canonically wants to torture someone indefinitely.
TL;DR: Tirek more overall effective in outcome endgames, Chrysalis is more interesting to think about in terms of "roads not taken in detail by the show," if you're sticking to villainy. Chrysalis has a more interesting MO, thought process, and goals.

Tirek and Chrysalis are evil in different ways, one might argue. Tirek is evil in that he's a destroyer/plunderer that's out for personal enrichment, whereas Chrysalis is a conqueror who seeks to twist what's around her to attain that goal. One of them will simply destroy society, the other will seek to warp it to suit them, if she's no longer in a stage where she's simply feasting on them as cattle with her indoctrinated subjects, acting as more or less her extended hooves.

> Also are we sure that Tirek wanted to destroy Equestria and kill everypony? I mean he was against allowing the Windogoes to turn Equestria into a frozen wasteland and absed on his lines like when he told the princesses that everypony would bow to his will it seems that his goal was to conquer Equestria and enslave the ponies which he was going to do in season 9 along with the others.
I think it's telling in regards to Tirek, that unlike Chrysalis (where ponies will serve as primarily food/slaves or her army/subjects/new hive, depending on if it's past S6 or before), Sombra, or Nightmare Moon , there's absolutely nothing pointing to what a society under Tirek would look like, as if he doesn't actually have a vision. The imagery involved in how he was gloating they would "bow to his will" was also accompanied by the subtextual imagery of him *crushing* the orbs representing the ponies, which is made damning by how he just seemed to be destroying everything in an alternate timeline where he *did* come out on top. When you think about it, literally *what*, unlike Sombra, Nightmare Moon, or Chrysalis (who has the aforementioned two possibilities) does Tirek want out of ponies, as part of his MO? He self-admittedly hates them in general, he seems to have zero desires for what a society under him looks like, and his goals involve making as many of them practically invalids as possible, all to make himself stronger. He *doesn't* seem to particularly care about having them worship his prowess. He seems to, at *best*, take what he wants, and move on to the nextsourplace of power to then repeat the process, because he's entitled to the power in his eyes.
Also, the Windigos objection was meant to be on the grounds of "if we leave them unchecked, that means they have a greater chance of directly threatening *us*, having let them grow stronger off all this disharmony" There was absolutely nothing about him caring about the future state of the kingdom in and of itself. Sure, he seemed willing as of S9 to have the others rule over what they want (and Cozy still has more inferable for what she might do), but there was still nothing on a *personal* level for that matter.

Tirek's comic can, more or less, be boiled down to showing that his grudge against Scorpan was completely unjustified, and that he was always, far as we can tell, a bad apple, and Discord's comment about daddy issues is honestly something people take too seriously, since Discord, an unreliable narrator as it is, was trying to piss him off, and implying that Tirek actually *cared* about the word of someone he utterly hated for not letting him be evil would accomplish such.
