Definitely form is important. Starting off light is important too. Personally, GMs were staple of my training for a long time, though I quit doing them back in December for simplicity. My erectors have a lot of mass in them and I never have problems with my lower back. I think it has helped my rowing strength considerably as well. I can row 1.25 x BW for 5 reps but can only bench 1 x BW for 5 reps, so it's probably partially due to that.
SLDLs are a bit easier to do properly than GMs, so if you decide to go with one of them, I'd go with SLDLs first. I love GMs but they are on par with squats in terms of the learning curve for mastering form, in my opinion. Just be sure to start off light, don't get all into your ego and go heavy before you are ready.
