Sometimes players don't realize they're at such a disadvantage. Sometimes they think you might still make a humongous mistake and lose that Queen. Sometimes they simply don't like quitting. Sometimes they just want to keep playing until the end. I see nothing wrong with any of those. I have seen many resignations in games that were still playable, even winnable or able to reach a stalemate. I understand a few of those times people may not want to resign just to annoy the opponent but I really think those are the minority.
is it better to lose or resign?
For me, I resign if I'm losing because it's a waste of my time if I'm clearly losing especially if you're playing someone who knows what they're doing.
I speak for myself because I've lost too many games when I had a clear advantage, didn't know how to handle it and my opponent ended up beating me even after being several pawns or pieces down. you never know what can happen

It's not good sportsmanship.
You mean people post in threads, without reading them, and without context?? HA!
And that action can make a thread into a "Hot Topic." Well DUH??
Never, never, never give up. - Winston Churchill
You do know Churchill resigned right?
Depends. At a lower level stay. but when you get to 2000+ elo just resign. Your opponent knows what they are doing.
yeah resign is not that bad but we should still not do it if you lose then atleast you learn something
All losses are treated the same, with regards to "points and rating adjustment", which is the OP's question. With regards to etiquette about playing on in a losing position, it's a bit situational and is really a matter of opinion. Personally, I think anyone rated below 1000 should always play to mate, not just because their opponent might blunder in return, but because both players need to gain experience, even if it is just how to mate with Q+K or R+K (or how to try and avoid it if your opponent doesn't know how!). You haven't won the game just because you're up material, unless your opponent decides to give it to you by resigning.
Once both players are above 1000 or so, then both should have those types of things down and neither needs that sort of experience and practice. But, if your opponent has the 2B, or has to mate you with B&N, play on. If they can't force the mate, they haven't won - they only have the potential to win (which both players start out with anyway).
Those aside, I think it is a bit spoiled sport to deny your opponent to play mate if it's on the board, particularly if they've just set up a very nice combination that leads to mate. Resigning rather than letting the person play out their idea so it can be recorded as part of the official game score (rather than get inserted as a comment at the end) seems petty to me, but obviously that's just an opinion, and others will feel differently.
Playing on when hopelessly down material, with no immediate mate on the board, isn't any fun and just drags the game on though. When playing online, by dragging the game on you are preventing someone else from playing another game (and yourself as well). So, while it's not against the rules, it seems pointless. But really, online games are just fun things to do, so dragging it out a bit is not really a huge cost to anyone involved and hardly something to get worked up about.
In an OTB tournament, you're wasting time defending a loss when you should be analysing your game to work out why you lost, and you're also taking away time from your opponent, who also probably wants to start preparing for their next round. Now, wasting someone's time does have an impact beyond a minor annoyance, and good sportsmanship dictates you should resign.
Anyway, in the end, though, if someone wants to play on, they are well within the rules of the game to continue because no matter how much of a material advantage you have, if you have not mated them you have not won so don't expect things to just be given to you without earning it. So if it annoys you that someone is still playing, then just mate them as fast as you can.
I personally get annoyed if I'm up a queen in an endgame or something and my opponent doesn't resign
