Suspension upgrades

Can anyone help me with their thoughts and opinions on the best upgrades for a 2019 MT07? One shop I spoke to said that ohlins are very overpriced and not worth the money they cost so I was hoping that fellow riders would be able to help. Cost is not an issue cause I’m going to be saving up for it anyway and I am not In a huge rush for it to happen!! Also another thing has anyone changed their seats ?
