Aluminum or steel doesn't really matter for most people. The aluminum arms weight a bit more and are probably stronger for severe impacts. The differences are really complicated but I'd personally focus on single or double adjustable and the diameter of the arm.

Assuming the steel ones you’re referencing are the Currie arms - double adjustability vs single adjustable.

The aluminum arms are double adjustable, where as the steel are single adjustable. The double adjustable arms allow you to make length changes without having to disconnect one end of the arm from the mount. Just makes it super easy to make pinion angle/caster angle adjustments.
Look into Core 4x4's tier 3 arms to save a few bucks. They have a JJ at one end and a rubber bushing at the other, which will still give you some good flex without putting too much stress on the arm mounts when articulating. Only down side to the Core arms are they don't offer double adjustable arms. Not a deal breaker, just have to work a little harder to make your adjustments. A floor jack and a block of wood makes it tolerable.
The Zone lift is a good starting point if you want to add on in the future. They are owned by the same company that owns BDS and JKS. I've run them on several of my Jeeps and never had any problems. Three years on my current Jeep and zero sag from the springs. I've had much more expensive lifts and my Jeep didn't do anything any better. It's a personal choice. It's your money to invest aka "throw away".
Assuming you do the higher tier core arms, they’re both JJs on both ends so I don’t think it really matters which brand. The Rokmen markets “heavy duty”, but I don’t think that really matters much.
Does this mean you have not seen anything from them or you don’t like anything from them
so, I’ve got a RE 3.5“ lift (I think 3.5) on my 2006 and assuming I can get a set of Savvy double adjustable Control arms without any delays with all the Covid stuff going on I’m replacing all 8 arms. The RE arms have been on my Tj for a couple of years, the front ones less because when my cam bolts came loose the front lowers were damaged enough I had to replace them (according to 4 wheel parts). Far as I know these are in decent shape, I’m putting in the double adjustable arms and eliminating the cam bolts and just doing them all while I’m at it and I’ll get better alignment all the way around. As I understand the downside to the RE although the initial cost is less they are somewhat less durable and they cost more to rebuild, like I said I’ve had em for a couple years and they’ve been OK banging around the desert washes and northern Sierra fire roads.
Now, all that said and depending on your budget I don’t have any plans for the old RE control arms you pay the shipping expenses and you can have my old arms if you want them, completely up to you. Also if anyone knows why using used control arms might be a bad idea please let us know I don’t want to unknowingly pass on any problem?
