Unfortunately, L2 is worth zilch for AIM or very small caps in main market. In both instances, market makers have the monopoly (or quasi-monopoly) of share trades.
This means they can operate in a cartel-like situation allowing them to advertise prices that are very different from what they actually offer for genuine trades.
By comparison, in the main market (except for the very small caps as mentioned above), market makers are not the only actors, so they are forced to abide by "rules" more due to the multiple other institutions actually offering to buy / sell shares. So then L2 is useful.
