I've heard good things about both. There's a thread in PBNation saying the CCM ss25 is a drop in upgrade. The check it upgrade appears to also be a drop in upgrade. Between that and the hush bolt I think you'd have a very smooth marker

I read the new CCM ss25 internals don't fart.

I have no experience with either.

Farting has less to do with the brand/design of internals than it does with the proper tuning of said internals. It's a balancing between reg pressure and valve/hammer spring pressure. When the gun farts the hammer is bouncing into the valve and opening it slightly.

Check it's kit is really just WGP internals, which are perfectly good, but might not really be any different from what you already have in your gun.

Changing the valve in an empire cocker would be waste of money. In fact many would be a downgrade. The only exception might be the new alien valve.

Eliminating hammer bounce is mostly a matter of tuning, like Ryn said. There's some good info in this thread:
War is an ugly thing, but not the ugliest of things. The decayed and degraded state of moral and patriotic feeling that thinks nothing is worth war is much worse. The person who has nothing for which he is willing to fight, nothing which is more important than his own personal safety, is a miserable creature and has no chance of being free unless made and kept so by the exertions of better men than himself.

I put the check-it internals into mine a while ago and it lowers the operating pressure sweet spot down a bit. I didn't like the bolt though, prefer the Tech-T Hush bolt. So, overall my pump stroke is quite a bit smoother, and my sweet spot on the reg moved from the stock 220ish down to 170ish. Sound signature is quieter, and farting is lessened, but unfortunately I haven't been able to tune it away completely yet (lazy). My velocity doesn't change when I don't hold the handle though, so I usually hold it loosely to keep it super quiet.

That new alien valve sounds sweet, but I don't feel like spending more money on another valve.
