I haven't seen following advantage of the cutter mentioned:
The cutter can masslock an anaconda but the anaconda can not masslock a cutter. I think it is the same for the corvette but haven't verified it myself.
In combination with its superior speed this is a significant advantage. The cutter has the option to low wake the other big ships don't have this option if fighting a cutter
DISCLAMER: I am an absolute NOOB in wing PVP. This is just all hypothetical theory...
In wing battles this could be a important advantage compared to the other big ships. If one wing has cutters and the other not the big ships of the side without cutter will have only the possibility to high wake. The cutters will have always the option to low wake.
If you choose the battlefield on a place where high-waked ships really take long to get back (e.g. Hutton Orbital

) it sounds like an important advantage.
Probably cutters will be the first target to get down because of that. Again because it is faster than the other big ships this could be used as an advantage for the cutter side. Perhaps they are able to fight the small ships with the big ships just having to watch.
For me the cutter could play an important role in the wing battles. It will keep mid distance. Always ready to mass lock fleeing ships and trying to divide the enemy small ships from the big ones.
Anyway I am a complete Noob in large wing PvP. It sounds reasonable to me. Perhaps Gluttonfang or other experts can tell if the above is complete bull




or not.
