Clutch fan vs derale single 2400cfm fan

Question guys I know this has been covered in other posts but want to see what u guys think.

So in front of me I have a Hayden clutch with a 18" fan. I do have a plastic Mopar shroud but doesn't seal the best.

I also have in front of me is this derale setup with wiring and relay and better alternator. I'll attach screen shot


I currently am running a flex fan that I want to do away with. The choice is mine since both in front of me but the problem I am currently having with the flex fan is once driving around totally fine except really hot days it does climb temp. When I idle in traffic it will go from 180 to 200 in about 4 minutes or so. I'll attached my current setup picture from when I measured before work

I bought a knock off champion radiator off eBay awhile back to replace my champion radiator that my flex fan destroyed during engine break in. Fan literally exploded.

I bought a cold case 2 row 1.25 tube size and want to pair it with best cooling option of the two and want to do away with my flex fan.

I see you said you returned it already, but I bought that exact fan years ago.....I recently gave it to my brother in law for free a few months back because it never even came close to what I needed it to do, and I was fairly certain it never made anywhere near advertised cfm.

He just has a stock 318, so I'm sure it'll be fine there, but hp=heat, and I was way beyond that thing even coming close.

Just one more opinion for the sake of the thread.
