I don't do it to myself, but I remember a long LONG time ago when I was still in the young adult exploration phase I went to a kink dungeon for a paid mutual messy session with a switch. Before the session I asked that at some pout she pour something into my pants. She asked the same question you asked and I said "Whatever you want." Near the end of the session, she grabbed a pitcher of goo, pulled out just the front of my pants, considered it for a moment, then said "I think your underwear needs some too" and...well there you go.
To this day still the hottest thing that ever happened to me.
To answer your question, probably the former now if I ever do it again.
When i get messy, i start wearing a boxershort and shirt. Love filing my boxershort but don't have anything overneath so i don't have to choose, haha.
I think the difference would be that between pants and underwear will soak the underwear and let the mess slowly and without lumps (in case of e.g. beans) through to the naughty bits. Whereas pouring directly in the underwear will gets your naughty bits messy at once. Guess with a more "massive" sensation. Maybe the sensation is perceived differently for males and females.
In my opinion the only right way is *your* way. Just try both to see what you like most
In the underwear, every time. You're not properly getting messy if you're clothes aren't completely filled. The mess should always reach the skin - whether you start fully clothed, in underwear or naked!
I realized a while back that self-gunging doesn't really "do it" for me. . .and it's been forever since I've gotten gunged by someone else. . .but that said, it's gotta be inside the boxers for me. I LOVE the feeling of something thick and sticky flowing down all over my pubes, my dick, and my balls.
@Tsarmina: Maybe you could give ladies boxershorts a try? Men's boxershorts have more room at the front that will take up more mess but probably not add (or even decrease) much to the sensations for a woman. Boxershorts will hold the mess at the bottom better than panties.
I went once so far to get this elastic bands with openings for buttons every 2 inches, together with the special double buttons to tie the ends together in a loop. I placed them high up my thighs, just above the bottom seam of my boxershorts to keep 3 kgs of baked beans in my boxershorts. Amazing sensation, to feel that much and pushing it around inside my boxershorts
Love pants filling it's a fantastic feeling I've used beans, porridge, soup, custard but my two favourites are custard and wallpaper paste both nice and slippy just where it counts.

Oh! Not at all!
There are plenty of other options out there; I was just explaining that my chosen one doesn't have a lot of it to hold things with, but it's still my preference!
Leggings, stretch jeans, or PVC (or leather or latex etc) gives extended holding power, but I still like things put inside the thong first!
Always directly inside my boxers, normally I tape them up around my thighs to hold it all in! I love the feeling as the slime gets higher and higher until it's at my waist
I found greek yoghurt very nice to let it run down in my boxershort. Thick, and it melts a little on your body, so a nice, fresh, slow substance to run in underwear.
Filling underwear by a hose seems also very exciting to me (only done scooping so far). Having the mess flow slowly in from a hose would allow to focus on the feeling of slow filling and distributing the mess around the naughty bits by itself.
