Yes they both lead to the same end goal but one is decidedly more fun than the other
When you have filler would you rather press 111111111 or press your buttons as a DPS
sure you can spreadsheet healer CD’s and DPS rotations but just because you can get both down mostly to the GCD doesn’t mean the healer side is remotely fun to actually execute and it’s unfair to say “well few people play healer so they should just accept the terrible design”
