Need to order Alternator, debating still.

Hello I've never posted here but been reading for years. I have always been able to find the info I need here, this time I've found most of it but still not sure which alternator I'm gonna buy.

Truck is 05 6.0. Pretty much stock now but is used for heavy work on the ranch. In the future it will have added lights and winch but nothing crazy. I pull alot of big trailers also. It also makes lots of short drives and sitting in pastures so not alot of time at high rpm to recharge

I have narrowed down to a few choices but just can't pull the trigger yet. A few of these alternators don't have the full numbers listed on their websites like idle output. I emailed to ask but has anyone actually tested any of these.

There are several alternator threads but I couldn't find a more recent one. Any and all input is appreciated and if anyone has the numbers on these alternators either real or what they say from the maker. Here are my top choices.....

DC is popular and have they say Hot idle at 100 amps. I like this choice but it is smaller amps than the other choices.
185 Amp OEM Powerstroke 6.0L High Output Alternator - 6.0L V8 Powerstroke Diesel - F-350 Super Duty - Ford - 2005 - Most Popular Products

I found a couple threads about Meen Green but they were older and couldn't find much info. Says 220 amps at 2000 rpm, I see nothing about idle output though. Very interested this one seems to have the most output potential but it doesn't list any other numbers.
Mean Green High Output Alternator 8306

And then I found powerbastards and they might be the favorite now. They say 220 amps at 1200 rpm! And idle at 110, these seem like the best numbers and they dyno test each unit before it ships.

Also was looking at the 200 amp version from these guys. I can't find any numbers on these website and they want you to buy some rectifier or something to make your alternator last longer. Didn't like that.

Oh and I can't find how many diodes some of these have? I read someone favored one of these because it had 12 instead of 6. I know it's essential for staying cool but can't figure out how many these have.

I'm leaning towards that right now, prices are close enough to not matter. Also should I just order one of the cable upgrade kits?

I have a couple 220A Powerbastards in my Fords, and have been fairly happy, no issues to speak of. They have them with undersized pulleys, be sure that yours comes with it so you won't have any chance of idle charging issues. Hope this helps.
