Yep. and it takes away from my verisimilitude as well. Any time a choice is being made for metagaming reasons as opposed to what the character him or herself might choose, that chips away the fun/realism for me. For example, in real life, people choose all kinds of weapons, not the one that does the max DPR. Either from cultural choices, or what just looks cool are the real reasons. So in the game, if you never have a PC using a scimitar because the longsword does more DPR, that just chips away at the fun for me. Just look at all the "Don't ever choose a great axe if you can use a great sword" comments we've had since 5e came out. For what? An extra .5 DPR? Screw that, my barbarian wants a great ax, and he'll get a great axe because that's what fits the theme.
Unified damage dice fixes that problem, IMO.
