I find nothing "ugly" about the first top except I might avoid the two-tone effect. Having said that, the second top reminds me of a '62 Thunderbird I salivated over once upon a time ... and unlike some things that tend to date me, I still think it looks quite effective. Now having said that, the first top may add more to the body's rigidity. And now having said that, rigidity may not be so much of an issue with a buggie.
A lot of help I am
I know
Wheels ... of three posted I like the second one best. It has a bit more three-dimensionality to them than the other two which I think is important with a compact design like your Manx.
Just remember with my opinions, you get what you pay for.
