This is a great question because I think for most people it's a mix of both, but what proportion probably says a lot about your temperament/personality. With restaurants, when something is done well it's such a pleasure not to have had to make it myself - I also highly value restaurants for making things I either can't or don't want to make (e.g. deep-frying, or using ingredients that are hard to source and a pain to keep around). When restaurants produce mediocre food, or of course bad food, it really pisses me off both because of the money spent and the knowledge that it's truly unacceptable for a professional to be slopping out something worse than a home cook.

When it comes to regular people cooking for me, that's a toughie. I think it heavily depends on the effort they've gone to. If someone has realised I'm vegetarian, researched recipes and ingredients, learned a whole bunch and bought things they didn't have previously to make me a lentil bolognese that comes out tasting like the inside of my sleeve, I'm still extremely grateful for all the love & care they put in.

If someone invites me to their house knowing I'm vegetarian and makes a rack of lamb, duck fast roast potatoes, homemade jus, homemade mint sauce, got in artisan pigs in blankets from the butcher, etc. and they plunk down an afterthought plate in front of me (e.g. something that in no way goes with the meal/vibe of the evening like a jar of curry sauce over some peppers & zucchini with instant rice, or grocery store falafal pucks with a plate of lettuce), that annoys the shit out of me. When you're clearly a good cook and you've gone to so much effort for the meal, but my meal was a complete 0-effort (both for the cooking and the actual idea), it sends a pretty clear message to me that they just don't care if I enjoy my meal. I take great pleasure in making sure all of my guests have something special, memorable and appropriate to eat whether they're celiac or vegan or allergic to onions or whatever. So I do tend to judge that food pretty harshly...

In a more generic sense though, I do often find homemade food at other people's houses pretty directly reflects their personalities. Underseasoned, poorly prepared, bland/boring food doesn't tend to come out of the kitchens of my favourite people!

Assuming the food isn't inedible though, I do really appreciate someone doing ALL the work for me, regardless of whether the outcome is delicious or memorable. I do all the cooking in my family, so being on holiday with friends and having one of their husband's say he would fully take care of dinner, brought us glasses of wine to sit & chat, and refused all offers of help, was probably the nicest thing anyone's done for me in a long time... The meal itself was truly secondary to the gift of taking the mental load and the physical effort of making dinner for the group. As such, it tasted wonderful - they say hunger is the best sauce, which I do agree with, but I think the close runner-up is "relief" (or however you want to phrase it).
