It is much easier to pull the weight when you can strap in and not worry about grip. A lot of commercial gyms won’t allow chalk, but I’ve never seen one that has a problem with straps. Commercial gyms also generally have shitty bars with shitty knurling, so without straps there’s a good chance that you’ll be limited more by grip than anything else.
I think in progressing specifically for deadlift, unless you’re getting ready for a meet it would be counter productive to not use straps.
I didn’t have to use straps for deadlifts until I moved and had to start going to a commercial gym and their bars were/are crap. I’m used to oakie bars that are smaller around in diameters and has knurling that digs into your hand and can draw blood, so you might be different.
