i have the Pro Standard one for the functions such as importing code and that stuff. if you want to add things like animations or do pro carrds, most of them use the pro standard. if you just want to have unlimited ammount of elements, high quality media well go with the pro lite. and if you need it to run a website kinda more professional the Pro Plus.

overall i've tried the pro lite and pro standard and i'll recommend the standard, with the pro lite you don't really notice you've got pro plan. but depends on your needs here are the comparision: https://try.carrd.co/lvjnsl
