not even close. you're usually the main focus trying to keep yourself and others alive(with 3 people on you), looking at ops window while also having awareness for what's happening on screen, deciding who should live and who isn't worth the resources at the time. switching to dps is extremely relaxing compared. i switched to dps because i want to play a game, not a job.
dps is NOT EVEN CLOSE to that.
people that think dps is so hard need to get over themselves and try being a healer against a good team. imo your best players should be in that role.
