Many are in transitional period and soon the question would be "who's not foiling". I heard a sarcastic and dismissive slur about TT calling it a "wakeboard". Nothing wrong with ramps and booties, or surfboards they're still guys in love with those - probably for many since they came from wakeboarding or surfing to start with
Personally, I started with stunt/revolution kites, T-ARC130 was my first quad kite back in 2003, rode landbord on handles on 3-5m kites for a while, kited with TT later on, got a kitesurboard, understood that for LW I need a door, along the journey my LW kite sizes went from 19m to 16m to 15m, my TT kite size went from 13m to 12m to 10m and back to 11m+9m to cover more of boosting range, added 7m and 5m later and sold the 15m LW kite because of foiling.
3 years ago I started with 2013 MHL Lift foil (long mast - aggressive learning), loved it, went to smaller board (DC 54"), went to faster wings (GW545 and that sucked but I wanted the 42" mast and smoother ride bad), went back to MHL, went to even smaller board (DC 42" and loved it), went to use hook and later when hook broke I went strapless, went to larger/thicker wing for GW (Moses 548), got a short mast for shallow waters of SPI/OBX, went to even larger/thicker wings for GW (Moses 590), added a huge wing (Moses 633) to cover LW wind range
Foiling is my form and shape of sailing and I love it. Still take my TT to boost on a 9m Turbine in 25-30 knots, but sold my LW kite this spring, and sold one of two door boards and selling all kitesurfboards. Foiling 70% of time and not taking TT to our local lake with gusty inland winds for last two years.
