"Honestly, a lot of the steel vs aluminum argument is over hyped. Get the wheels that you like."
Agreed....I tend to like alloy wheels best - I also think the weight savings in old jeeps that have trouble getting out of their own way might be helpful - but it probably isn't significant. I've run allow wheels on my cj7 and now my cj5 - they've been used pretty hard - and never had an issue with durability. I am running mag slots from the 70's right now! I think there are some application where steel wheels are appropriate for aesthetics or 'just look right' etc... choose the wheels that are the right look and price for what you want. Honestly, I'd polish up your steel wheels and keep using them with a 4 tire rotation. You know me, I am kind of cheap, but I'd buy 4 new tires and put them on, and take the best of the used etc and put it on your spare and call it good.
