Unless a few ounces of weight saving are vital to the racing you might be doing I would choose the version with the looks you are attracted to.
Looks like you have missed the March WM two-for-one pricing on new Lewmar winches this year. Darn! I used that sale to upgrade our pair of housetop winches from 30ST (factory stock) to 40ST in 2018. I correctly repositioned some new clutches during the same upgrade. What model and year is your boat? Please put some basic info into an sig line; this helps others here to give more relevant info.
The larger ratio winches are, IMHO, a safety upgrade as well. Having a friend winch me up the mast for any reason was really a big "ask" with the old winches -- much easier now. That would also be important if you have to use your Lifesling (r) to lift a COB up and out of the sea. Check my blog on this site for a poor attempt to document this upgrade.
