Fish vs funboard

Hi,
I am 16 years old and have been surfing for 3 years. (about 6 weeks surfing). I have just saved up to buy a board and currently have enough to purchase a torq fish. This has always been the board I have wanted to get but I am starting to have doubts.
I am 5”5 and weigh 55kg and swim competitively so am quite fit.
When I rent I rent a torq funboard in 6”8. I am comfortable on green ways and can turn confidently but find the board is holding me back slightly.
I am considering a torq funboard in 6”8, a torq fish in 6”3, or a gul cross mod fish.
I generally surf in Devon/Cornwall at 2-4ft but want something I could also take on public transport.
Could you give me any advice on either of these models or something else to consider?
