If you're not powerlifting/want to get a bigger deadlift. I would probably stick with stiff legged deadlift. I would never skip all deadlifts variation though, it is a good movement when done properly.
There's plenty of dudes deadlifting reasonable amount without any size to show it off (Johnny Candito and Omar Isuf comes to mind). There's also plenty of big dude that deadlift heavy often. But then again, what size can you really get at 160-180 lbs natty?
just my 2 cents
