Normal mode in Trilogy = Easy mode in CG versions. But you are still offered 3 difficulty settings. Just choose Veteran because Normal is way too easy.
The story overall in the trilogy still doesn't make much sense, but I think that's due to the fact that they didn't plan it as a trilogy. Or the writers are bad at it. For the first game, they did remove the plot point of Metroid Prime running around despite the game stating that it has been locked away. The package comes with an art booklet that clears... some things up.
Changes I noticed:
-Bloom lighting for the first 2 games. It's subtle which I like because I think in MP3 they overdid it in some parts.
-Disabled some sequence breaking aspects. I don't really care at all but some people are crying over it.
-Upped the texture quality. Places look a bit crisper but it's hard to notice because you can't compare directly. GC versions do look rather blurry if you put it side by side.
-Load times are significantly shorter in first 2 games compared to GC.
-Certain PAL additions/changes are added. For example, you meet Fission Metroids much earlier in the first game.
-Some Echoes bosses are easier.
-Chozo Ghosts take 1 super missile to take down now. But they are still ****ing annoying because they spawn everywhere.
With free aim, it's much easier to take down certain enemies now that you can lead your shots. Remember the invisible robot sentry in Phazon mines that you couldn't lock-on to? Now he's easy. In fact, any enemy that can disengage your auto-locking before in the GC version can be finished off with ease.
I like Echoes the most of the 3, which seems to be a rare sentiment among fans. Felt like the developers took more of a creative initiative despite relying on some horrendous moments of back-tracking, item searching and other face-palming flawed ideas.
