I need some information on Fujifilm

I am looking to move into a new camera ecosystem - and I am stuck deciding between OM System and Fuji, and the main deciding factor is weather sealing, I want something that can handle aggressive downpours and a lot of dust/sand (No, I can't get a Pentax) and in that case I really like the IP53 rating of the M4/3 cameras, but I also heard the X-T series is reliably weather sealed, what do you all think?
