Worth upgrading to a VSF?

Hi all,

I bought this clean submariner in 2021, so it‘s 4 years old but still runs without issues.

During that time I bought a few other reps but still the no date sub has the most weartime, very good daily watch (when prices crash I might go gen at some point).

Currently I was considering to buy the same watch again and to upgrade to latest rep of VSF. Would you say my clean is still a good rep and is it there even a difference to the latest VSF no sub model?

Many thanks to all!
