Easy Quirk is the one that can be realized, or performed at a high level with little difficulty, time, or effort.
Bad Quirk is self-explanatory. Quirk that in majority of situations would be quite below average or useless.
For those unfamiliar, Hero classes are actually sitting in the alphabetical order of a traditional system ordering kana characters by their component phonemes called Gojūon.
The system as it follows:
A, I, U, E, O
Ka, Ki, Ku, Ke, Ko
Sa, Shi, Su, Se, So
Ta, Chi, Tsu, Te, To
Na, Ni, Nu, Ne, No
Ha, Hi, Fu, He, Ho
Ma, Mi, Mu, Me, Mo
Ya, Yu, Yo
Ra, Ri, Ru, Re, Ro
Wa, Wo
N
As you can see it starts with A and then goes left to right. In case of the same letter, next kana is taken to determine who sits first. As such Aoyama is sitting before Ashido because "shi" goes after "O" and Tsu is after Mina because "su" in Asui goes after "shi". If surnames are identical in sounds like in case of a sibling, they go to names.
Of course those kana can be read differently. For example K sounds also can be read as G sounds, B, P and H are following each other(which is why Bakugo is sitting after Hagakure), T can be read as D(which is why Midoriya sits before Mineta) and someone like Jiro ended up between Shoji and Sero because "ji" sound falls after "sho" which is after "shi" but before "se". 'S' in general is also followed by "Z" sound too
In my OC's case his surname is Naori so he sits after Todoroki who is his friend. Since he replaced Sato however(who is in 1-B), the order changed a bit so on his right is Shoji whom he respects and on his left is Momo with whom he is also a close friend. Overall he is chilling.
Of course your headcanon doesn't have to follow it but I found it quite interesting to see where everyone would be in seating order.
Moderate Quirk is the one that isn't easy to master but also isn't outright difficult(unless the training is flawed). It still needs a noticeable amount of work and effort put into it to make most of it
Decent Quirk is the one that is pretty satisfactory, above average and even respectable but not outright good.
Also finding clear anime image of non-boosted Gearshift being used was a pain
Difficult Quirk is the one that requires a lot of practice, time, and dedication to achieve most of its effects or to be made of use in general

Bad Quirk is self-explanatory. Quirk that is in majority of situations would be quite below average or useless.
"Not worth the effort" is the Quirk that is so hard to use that most people might as well give up, whether because it is too difficult to make it of use or hurts them(the exceptions of people who use them anyway exist however).
Amazing Quirk is the one that is generally considered and often can be most impressive, exceptional or powerful
"Not worth the effort" is the Quirk that is so hard to use that most people might as well give up, whether because it is too difficult to make it of use or hurts them(the exceptions of people who use them anyway exist however).
Good Quirk is the one that is usually desirable and can be seen as quite great but not outright amazing
As chart suggests, community's opinion on quirks. Just a fun poll. Columns are about how good/bad is the quirk.
Rows are about how much effort/suffering one has to put into developing their quirk to be useful e.g "Not worth the effort" being so hard to use that most people might as well give up, whether because it is too difficult to use or hurts them(the exceptions of people who use them anyway exist however) while effortless means practically little to no training to get most of the quirk's effects
