I enjoy the leveling up aspect of the weapons in Ratchet. However, the series has been stuck for a while; 6 games in 6 years will do that to you.
The Jak series was pretty good, but I wasn't exactly a fan of the GTA change.
The first Sly was great, and each proceeding game improved on the formula. I'm really hoping for another Sly.
Overall, I think I enjoyed Ratchet more, but Sly is definitely the better series.
