So I wanted to pick between the three to purchase, even though I don’t mind grinding per se but I wanted to see which ones were worth getting based on “fun” factor.

I know it’s a subjective type of question, but in terms of abilities and such, which offers the most versatility and interesting or exciting ability use? Is there one that stands out best among the three?

I generally enjoy frames that allow me to decimate enemy mobs and waves but also help the team with a fun supportive kit or something that like keeps everyone alive long enough to sustain or like wipe all the mobs out with little effort needed. If there’s one that stands out for being “immortal” type or like has huge survivability that would help a lot since I enjoy being tanky and not dying as often.
