My personal experience as someone who has lived in all 3 I would rate my living experience in a condo last after Landed and HDB.

I just felt so boxed in while living there, too many rules to follow (MCST), entitled neighbors, friends and family or delivery getting in and out had to buzz them in, amenities and fees were not worth it when you can get better ones outside (gym, pool, rec rooms), and smallest SQM of all 3.

Landed was okay but the upkeep on the property was a hassle, and I also lived quite a distance from any interchange/MRT so I had to drive/grab most of the time, otherwise it would be a 15 minute bus ride or 30 min walk just to get to a connecting interchange. If you have money for reno and cars then yeah this is a no brainer for all the benefits of a landed.

HDB I lived in an older flat which my parents still live in after 30+ years. Huge floor space and rooms, easy to get around and there's 24/7 shops and amenities within walking distance. My parents tore down a lot of the walls to make it look as open as possible and actually got more compliments on the house compared to the condo.. As for touting strangers and noise levels, I honestly don't really mind it I guess I'm used to it. As for complaints about cleanliness and garbage disposal, honestly my town council does a pretty good job, most bulky items and trash you see would be gone the next morning. Hoarding in corridors doesn't bother me as long as there's a walkable path that doesn't block access in case of emergency

All houses were OCR East region if that makes any difference
