I'm back in the game after being away for about 3 years.
Now that alchemy orbs and fire crystals are a thing, is it more efficient to roll UVs on low level gear, then level it? Or is it faster to spend the energy to UV-roll my current level 10 5* sets?

There's a third strategy, which is to buy the UVs (on 2- and 3-star items) from other players, and upgrade from there. Often you can find UVs on the Auction House for less than Punch would cost you. And how much would Punch cost you? I have a detailed guide on that. The later parts aren't done yet, but the earlier parts are probably what you want anyway.

The precise answer to your question depends on how much you enjoy farming Radiant Fire Crystals, because those are really the bottleneck to progress now. My guess is that these are your strategies, ranked from best to worst:
1. Use Punch on your fully heated 5-star items. Just be aware of how much it's going to cost you, from my guide.
2. Buy low-star UVs from other players and upgrade them yourself, locking the UVs on each upgrade of course.
3. Make new low-star items, upgrade them in the hopes that they will acquire UVs through crafting, and use Punch at the 5-star level if they don't have UVs that you like yet.
4. Make new low-star items, use Punch on them, and then upgrade them, locking the UVs on each upgrade.
Oh, and welcome back.
