The strongest argument for moving to Woodlands would be money, and thats a major argument. I dont think you can rent a 1500 sqf
condo apartment for less than 2.5 K anywhere else in Singapore.
I have been living in Woodlands for some time and I'm quite happy with it. Its definitely much more quiet than Orchard or Toah Payoh and the air is cleaner.
It does of course take some time to travel downtown from Woodlands, but at the same time it is in general easier to get to the MRT here than in central areas. Where is your workplace? If it is at Jurong or further west it will probably not take any longer to travel there from Woodlands than from Orchard.
Woodlands is definitely suburban, and by far dominated by HDBs (with corresponding amenities), which may or may not be a good thing. There are lots of foodcourts, but personally I think the food here is pretty crappy (compared to foodcourts in both neighboring Yishun and in Orchard).
If you consider to rent a condo in Woodlands I would advise you to read this thread first:
