Good modern full foot fins have very soft foot pockets, compared to 10, 15, 20 years ago, and compared to cheap third world rentals. That said, vacation snorkelers will probably blister no matter how soft the foot pocket; we don't call you tender foots for nothing. Apollo Bio-Fins are a better split fin in many opinions; they come in both full foot and strap. Full foot fins transfer the power of the kick much more efficiently than strap fins. I am not a fan of splits, probably because I came down in horse power from free dive fins. As an instructor/guide, dragging students/guests in strong current requires a paddle IMHO.
Mares Volo's also come in full foot or strap. I have had many Mares fins, including Volo's. They are very powerful, but some of the power is from soft materials that don't last as long as their less high tech models. I currently use strap Avanti X3's but will get Quattro's next; both last a lot longer than Volo's. For Beach diving, I loved my full foot Mares HP's (stolen), which Mares replaced with the Superchannel's. Some people wear thin neoprene socks inside the full foot fin; a little warmth, blister and scrape protection.
The choice depends on where you are diving and what kind of diving. If you are only diving tropical waters from boat or soft sand beach, full foot is not a problem except mid day when the sand is very hot on feet that don't walk there every day. Most tropical and sub-tropical waters do not have thermoclines; it is rare to have 3 deg change at 130' here in Hawaii. If you are diving from rocky shores, walking in gear from the parking lot or down/up stairs or in colder water, strap fins and boots are the way to go. If you are a total tender foot, strap fins are the way to go.
As a beginner, I would recommend a reasonable priced fin to start. Nothing pisses divers of more than paying $200 for fins that they replace in 20 dives.
Here is a link with Mares full foot Superchannel's for $60 or strap Avanti Quattro's for $100. That's the most I would spend as a noob. Many people will tell you to at least try fins in a pool before you buy, but with full dive gear in the ocean current your pool test may not have worked. Trying different fins on actual real world dives is the only way to really know what you like!
Twin Jets are a Scubapro split fin, of questionable worth in many eyes. Jets are a serviceable 40 year old semi-paddle design made by many companies, but only a few now with modern materials, that are very popular with the guys who only wear black gear; technical, cave, DIR, GUE.
