Are your guests traveling? Answer that before you compare a single feature list. Every wedding website carries a schedule, an RSVP form and a page of details, so the platforms separate on what sits around that, and nothing separates them as hard as travel.
A wedding across town needs a page guests read once and a form they fill in. A wedding where eighty people fly in needs rooms held at a hotel, arrival times, who is staying where, and a way for guests to pay for their own beds without you running a front desk.
So the thing to check on any platform you are considering is what it does with rooms. Is accommodation a text box you type a hotel name into, or a list of rooms a guest can book against and pay for? That one difference is worth more than template counts, and it is the difference this site was built around: we booked out a hotel in South Tyrol for our own wedding, the hotel sent one bill, and there was no way to collect from guests.
