EDIT: I'm not sure you have access to all V-Collection presets if you only have Analog Lab. I think perhaps you has'nt. EDIT END. Have you looked at at the product pages?
EDIT2_ I've just checked. On the product pages i says Analog Lab has over 6500 presets and the V-Collection has over 8000 presets. So it's not the same amount. EDIT2 END. I'm not sure if this only is because of V-Collections included xtra soundpack, that's not a part of Analog Lab as such.
It's the same software.
Without having the full individual applications in the V-Collection, you are limited to use the parameters availble in Analog Lab. The full applications give you full control over the sounds.
