EK-KIT X360 vs EK-KIT P360

[Rampy216]

I wanted to get into water cooling and I've been thinking about getting the EKWB EK-KIT P360 but then I noticed that the price of the EK-KIT X360 isnt that much higher. I know the radiator in the x360 is thicker but it has less fins and the radiator in the p360 has more fins but its slimmer and although I assume the x360 is better, Im not sure if it'll fit with everything (I want to put the radiator in the front of the case). I have a define S and Im looking for a very quiet PC (thats why Im getting into watercooling).
other suggestions are welcome

The differences between the kits are the pump and the radiator. Just go for any of both which can fit in your case.

I know I can fit the thicker radiator in my case but I dont know if it will fit with the pump and res
