The g/f use to be a hair dresser and i know she use to pay up to £80-90 for scissors.
There is certainly more design in aquarium scissors, they are longer for a start and will definitely be made from a quality steel. I can imagine they are similar to some surgery scissors.
Whether you could justify spending £110 on a pair of scissors to support your hobby is another question.
I SWEAR to god i am not joking, i use a tiny pair of scissors that i got from a posh Xmas cracker. I am putting my ALL into my next tank to make it succesfull and i can honestly say i am happy with them lol.
They are super sharp and awesome little things. In my opinion, you either need them long or tiny, either way the blade should be sharp for a clean cut. If you start crushing the ends you may damage the plant for regrowth.
If you use normal size scissors the blade is too long and gets in the way, thats why imo you are best with very small ones or long handles.
