You only posted part of the info (lacking context). So I can see the TPVV's LD's span many more disks so it potentially has more performance, assuming this is raid 1 it will write 256K then move to the next chunklet but I can't see the underlying geometry of the VV's or CPG's so can't see how you ended up with the LD's you got.
Because of the very small size of the FPVV and the fact that it's fully provisioned it will only ever span those 4 chunklets, so yes the TPVV has more potential performance. You can see the odd numbered PD's are aligned with one set of LD's belonging to one node and the even PD's the other LD's and node. Much will depend on how much data actually gets written, but given how small this is(it'll fit in cache) performance between the two will probably be variable/marginal anyway, why don't you test it ?
Have a look here for the VV sizing and CPG growth formulas.
