Heroes not wanting superpowers is pretty common tho so this reason is pretty bad.
SPOILER ALERT FOR ANYONE WHO NEVER READS ANY BLUE BEETLE STORIES
As for me, I love Jaime Reyes' Blue Beetle because his interaction with the scarab, Khadi Ja is entertaining. Even if you don't understand what the scarab is saying it's still entertaining to see Jaime interacting with the scarab.
Other than that this Blue Beetle focus more on family. The whole family knew about Jaime's power since the beginning of Blue Beetle 2006 comic series. You'll see them supporting Jaime when he's feeling down or still being like a normal family where Jaime needs to do his homework and chores first before saving the day.
Also Blue Beetle here is one of the dc heroes that doesn't meet the predecessor of the hero name he holds. That's because Ted Kord died when Jaime becomes blue beetle in the original series. So Jaime Reyes have never met Ted Kord. He is mentored by Peacekeeper instead. From what I remember, their dynamic is pretty fun too.
Blue Beetle 2006 comic series, from issues 1 to 25 is the best one imo. It's entertaining, funny, wholesome and it centers a lot on family love.
The new 52 and Rebirth have Jaime having rebellious teenager phase so it can be a bit turn off reading those comics. In the original series and in both tv series Jaime is in (Batman Brave and Bold and Young Justice) he's pretty laid back.
Overall I really love Jaime Reyes' Blue Beetle. He's one of my favourite dc heroes so the reason that Blue Beetle is unique statement is not good enough.
