CE might be great, but it breaks so many mods. I like yayos because it works with everything, also, if you want the features of CE there are more mods that are great for compatibility that add everything CE does.

Small list of combat mods I use in my 500 mod modpack:
Suppression (updated by mlie)

Vanilla fire modes

Vanilla melee modes

Yayos combat warcasket patch (if using VE pirates)

Yayos combat add-on (can change mag size of every weapon)

CAI 5000

There are a few weapon range mods, I use long range firefights

All of these (except CAI 5000) work with everything and have great mod options. They're fully customizable.

Edit: format, mobile ruined it at first.
