We have a twin floor bed in a Privacy Pop tent and everyone in the family loves it. Its plenty big enough to cuddle up in and when we close up the flap it gives him the enclosed feeling of his tent, he naps and sleeps the same overnight, etc. We did have to lock him in his room for a bit but now he just waits for us to get him and sings to himself.

Is your son an escape artist in general? We moved my daughter to a queen at 2.5 and it was easy. We already had the bed so it made sense to use the Queen - lots of space if one of us ends up in there!
However my son (2 and still in crib) will be a disaster I think and we will keep crib as long as possible. He can climb out of the lowest setting so now he essentially has a floor bed inside the crib frame (his frame goes really low). But also set up (for future and sister's occasional use) is the IKEA daybed. I love it! Looks nice, the daybed frame helps make it reasonable for me to lay down in it with him (vs falling out of a regular twin with no backing), and great storage underneath if you need it. It's great if you don't have space for a bigger bed. We can also all 4 sit in it for story time.

We took off the rail to make a toddler bed and it's been a great decision for us. Since it's still basically the exact same thing as before, just now a "bed" instead of a "crib", her sleep was not disrupted in any way. I prefer not to get into bed with her and start habits like that, so the small size works in our favor.

My child was and is not a great sleeper and is very stubborn. With that said, we moved her into a queen.

In our situation, we had a queen bed and her crib jammed into her room already. So when she would wake up early often DH or I would come in and cuddle her back to sleep in the bed anyway. She started screaming bloody murder when we put her in the crib, so we started letting her sleep in the bed. Worked for a few days then she started getting up over and over again, so we ended up putting her back in the crib (which we never removed since baby sister would need it soon). A few months later we did it again and it stuck but occasionally DH will still have to sleep in there with her.

So I vote big bed.

We had no reason to move our son but we did as we travel a lot and he outgrew his travel crib and would not sleep in a bed in a strange place. So we got an IKEA twin with a rail and talked it up with books and made the move on a Friday night 2 months ago. He is literally in love with his bed and there has been no negative impact on his sleep besides taking a little longer to fall asleep the first night. Knock on wood he has never gotten out of it during nap or night time. We will do a queen when he's older but the twin is a great size. Mostly it was affordable and we can still get in it with him. He plays in it and 'reads' in it and puts us to bed in it too ha
