Of all three, i would definitely place LBS at the last tier.

Kinda like a toss between IJM and Mah Sing -- IJM is abit more focused on townships, so there are boosters you can hope on to push prices higher.

MS tends to go rambo, buying random land plots here n there and then build those 40, 50-storey high shoeboxes to maximize ROI in a short period of time

More importantly, price and location is far more important than who the developer is lah
