Yes and no. The 15s were quite heavy. The 14s had too low an offset, and so were lousy on the hillclimbs. But they were a cheap set for £90 with tyres. I don't think there is such a thing as "right banana". Its more of a case of hype. When I had a set back in 1997, people had no clue what they were. There isn't a single model of Watanabe for the MX6.
The Panasports looked nicer. These Maxilites are closer to the original design from Minilite rather than the Watanabe knock-off (the relationship with Minilite has never been clear). Not many MX5s out there on Minilites (a few). You can't beat the look of the M2-1001.
Panasports would be my preferred choice, but funds don't go that far.
