Shaping top of sleeve

I am working on a cable sweater and am at the part in the sleeve when it is time to decrease on each side. What technique of decrease will look the best? RS and for WS?

Thank you so much. Happy New Year!

I like the decreases to follow the line of the sleeve cap (ssk at the beginning of a knit row and k2tog at the end of the row). For the purl side that would be p2tog at the beginning of the row and p2tog tbl at the end of row.
But it’s a matter of personal preference here.
