Not tried the Fatip, but the 25C is a nice gentle shave with a nice grippy handle. It is quite light but can still just about get away with just two passes for me, so it shaves close enough too.
Actually, I have a nearly new 25C (mint) that I would let go for £20 posted in the UK, including a new pack of blades and a cheap Boots DE razor as a back-up/travel razor. Let me know if you are interested.
They are very nice, I just prefer heavier razors now.
