Help with Boss hunting difficultly list?

My friend and I recently got back into maple, he made a new Aran whose close to 170 and I'm close to 175, we aren't necessarily funded, haven't enhanced our equips with traces and added star enhancements,YET. We enjoy boss hunting and just wanted to know what's good and fun to try, we've cleared the following while duoing & Soloing:

Easy/Normal Zak
Easy/Normal Horntail
Easy Gollux
Easy Magnus
Possibly Easy or normal Hilla & Von Leon, I can't remember which one it was, but I remember killing them both.

Myself currently buffed is: 123k - 137k , we aren't really into pay to win or have insane funding but we can get around. What's the recommended level and damage range to fight Bosses like Chaos Zak and Chaos Horn Tail, Some people say they are easier than Normal Magnus, even though Magnus only has 6 B hp, while C zak and HT have maybe over 100 B or something.

If you're experienced with bossing could you leave a difficulty list of all bosses or bosses you've faced, with your thoughts beside it, example:

-Pink Bean
-Cygnus
-Hard Magnus - Be (Lv 200+ with 300k Range, watch out for mechanics, etc)

Thanks in advance.
