Take this with a grain of salt, this is all very subjective
I have not paddled Atlantic LV, so really I can not comment how it would handle for you.
I am 5.9x150, so the rest of comparison might be relevant.
I find that I, personally, tend to overpower Avocet LV, Pilgrim, Xcite-S, all boats in the similar class - they pop out of the water without me giving them 100%. I also find that they sit a bit too low in the water for my liking, and that is without even a day kit. I don't think you could pack camping supplies in it.
Speedwise, you shouldn't have any difficulties keeping up with the longer boats, especially in xcite-s. Atlantic LV seems a bit more conventional design.
If you still decide to stick with these 2 boats, I would definitely go with xcite-s - construction is totally bomber, it is marginally slimmer, surfs anything.
If you haven't made a decision yet, I would encourage you to try SKUK Pilgrim Expedition ( the longer version of Pilgrim), and Xcite.
