I am looking for some suggestions about which Canon Speedlite I should consider purchasing. My camera bodies are Rebel T6 digital and an EOS 630 for film. Mostly hobby use but I did shoot a couple of weddings for friends. I’m considering either the 580EX or 580EX-II. I can’t justify the expense of the newer 600EX series units for my usage but have seen the flashes I am looking at for about $100.
The 580EX II recycles a lot faster than the previous model. Both would work fine on your cameras, although the older film camera won't be able to take full advantage of some of the flash's features.
BTW, the earlier 550EX is a very good flash, too. And all of them can be sped up recycling by using rechargeable AA batteries in them and/or using a Canon CP-E(series) auxiliary battery pack, which plug right in to the 550/580/600EX series models (and only those models.... don't work with 400/300/200-series models).

Whatever you get, make sure it's an EXll, not the non ll. I don't believe the non ll is ettl. Definitely you want ettl....
EDIT:
ALL 500-series EX FLASHES ARE ETTL. In fact, I think all EX flashes are ETTL... period... regardless of series. Some of the newest models are ETTL II. The difference with that is that when used with certain newer and possibly with specific lenses ETTL II is a modest refinement of the already very good ETTL. Original ETTL (all EX type Canon flashes) provides "through the lens" metered control of flash output.... ETTL II does the same, plus it can utilize distance info generated by the lens focus with certain lens and camera combinations... However, I'm not sure about either of your cameras and don't know what lenses you are using on them, so might not matter in your case. When camera and lens don't support ETTL II, the flash automatically reverts to standard ETTL.
The 500-series flashes also can act either as master or slave in multi-flash setups (most 400/300/200 series can only be used as slave... one exception I know if is the tiny 90EX, which can act as a master controller).
500/600 series Canon flashes are pretty large and powerful. If you have chance, compare in person with 400-series and others, to be sure you are okay with the size.
Most third party such as Yongnuo, Godox, etc. emulate and are similar size/weight as 500/600 series models (3rd party can be cheaper, but are not as well made as the Canon).
There are add-on modules available from third party to be able to remotely radio control and trigger the 500 series (instead of optical), same as the "R" series models. This is much more versatile than the "optical" remote control/triggering built into the 500-series and similar.
