As someone who had no experience with CE or H2 until recently, I wouldn't have known anything with CE was out of the ordinary. The main issue with that game, which I think has existed since CE Anniversary on the X360, is that the remastered environments use the collision data from the originals. That's not a great way to explain it so I'll give an example. You might find that if you shoot beside a tree with the remastered graphics, your bullets will hit an invisible wall. This is because the tree in the old version was bigger, and you're actually shooting it. The tree on the remastered graphics is smaller but they haven't adjusted the collision detection to match it. This happens with a variety of objects, walls and surfaces. It happened to me a few times but didn't really affect my enjoyment of the game.
For H2 (Anniversary), the game runs mostly smooth on PC, although it does occasionally stutter in some areas where it seems to be loading things in the background. This issue doesn't seem to be present on any of the other games in the collection.
About 2/3 of the way through H3 now - not got much to do in the evenings at the moment so I'm flying through them. The most standout thing to comment on is that it's much, much easier than the previous titles. There hasn't really been a fight yet that's taken me more than 2 goes. I feel like this game probably has the best vehicle sections of the trilogy so far. Given how the ally AI can be, I'm glad they've made enemies die quicker. Equipment was a cool addition that allows for some new tactics. Some of them don't seem useful against the AI though and only serve to make your own life more difficult (Solar Flare / Radar Jammer).
