1st: is it a True Mono Cartridge? Always ask that. No signal generated by vertical motion is what you want.
next: what stylus profile shape?
then the cantilever material? because good mono can be VERY Dynamic
tracking force? (a lot has to be right to track lightly and get excellent measurements).
the combination of light tracking with large contact area of advanced stylus shapes is my preference, which has both longer stylus life and less wear to the grooves. Stereo or Mono
last: tech talk/achieved results/specifications, my copper is better than your copper
cartridges, SUT, cameras, at first I want to run from the technical crap, but after a while, it’s not that complicated, I’m a college graduate for god’s sake (art school) .....
Of your choices, two are conical, no way would I consider them, the Grado ME+ is elliptical, Ortofon Quintet Mono is Elliptical, both on aluminum, Ortofon a lot more $
I would definitely go for an advanced stylus profile for your system
Hana is Shibata on tapered aluminum

Ortofon 2M Mono SE VERSION is Shibata (the basic Ortofon 2M Mono is conical)

My AT33 Mono, I like MC technology and the tech, but not like the aluminum cantilever or conical tip,
which is why I searched for a broken one, and had VAS rebuild with boron/microridge (nowhere available to purchase).
Yahoo Auctions $40. including Aledo fees/bank fees/shipping in Japan. Air shipping to usa $30 (should have chosen surface ship). VAS $400. total $470. plus 2 round trips 35 min each way, gas and tolls, I call it $600. total. It sounds awesome!
One of my used AT160ml was also Yahoo Auction, win auction cost $160.,
aledo fees/bank fee/ship in Japan to Aleado. ship to usa: $63, total $223.

I’m a bargain hunter and willing to take risk, you win/you lose: I may lose -$250. on the tonearm I bought from Germany that had to be rewired, time will tell, seller is stalling. Or, it’s total price will be $404. incl customs and shipping to usa + $250 VAS rewire = $654. I’m not crying or giving up yet. My search: the only arm that fits in that location with a removable headshell
