Brett Martin vs FloPlast Square Guttering

[hadlowj]

In the process of replacing all the guttering on the house, I am swapping from 112mm half-round to 114mm square but have come to a difficult choice, FloPlast Vs Brett Martin, There is not much in it price-wise, I can't find many reviews comparing them either. From a look at the images the FloPlast seems to have a wider seal but apart from that I can not tell much difference. What are peoples opinions on which is best?

Many thanks

It doesn’t really matter between the two. Why not go for deepflow gutter? (Deep round).

Almost double the price and like the look of the square over the half-round.

I use floplast, mainly because my local Screfix is 4 minutes away
