I like both, but find tofu is more versatile and easy for me to work with. However, I try to keep my soy intake to a minimum due to thyroid issues (a few servings a week average is ok). I have really only mastered a few recipes with vital wheat gluten/seitan homemade so I don't eat it very often either, maybe once a month or so. I don't like commercial prepared seitan much. I am more of a dried beans person, and eat those daily. Tempeh I eat maybe several times a month. Lentils I eat four or five servings a week. Chickpeas, kidney beans, black beans, lima beans/peas, and white or navy beans I alternate and eat several servings daily and have for years. I never tire of beans.
And mushrooms I could live on lol.
I would eat tofu and drink soy milk a lot more if it didn't drive up my TSH and cause my thyroid meds to not work as well. If I just space it out and eat it a few times a week no big deal but not daily.
I was never a big meat eater and I remember even when I was very young being repulsed by a lot of meat. I remember refusing to eat red meat at the dinner table when I was little, and my Mom yelling at me for being picky. When I was an omni I would force myself to eat a lot of fish, eggs, occasional bird meat because it was "healthy" but I didn't enjoy it all that much. I couldn't stand the texture and smell of a lot of the tougher meats. The texture of eggs never bothered me, but the yolk would sometimes gross me out lol. I would eat hard boiled eggs a lot back in the day as a snack or with breakfast.
I could seriously eat the extra firm tofu plain, as is.
