Fenix 6 Pro or 6X Pro

Hi there, I am looking to upgrade from a Fenix 5. I am looking at the Fenix 6Pro, however I am finding the price difference between the 2 is only about 15 USD (6X Pro on sale in one of the shops). 

Logically, think makes sense to go for the 6X pro but am worried about being too big/heavy. Also I have an existing set of 3rd party 22mm watch bands which will work with 6 series I think but dont want to lose out if the 6X is the right watch to go for.

Any opinions from current owners of either watches please?  For reference, I am a big bloke with big hands, so usually big watches are not an issue but fenix 5 is too big at times.
