U can read the respective threads on actual users for comparison. Since last week Celcom has rectified they problems. & most of usual oledi got bck to their normal speed and some even got more than what they expected

(i.e speed exceeeding 1mbps!!)
However not so sure how long it will sustain at this speed...Right now at 3G areas, on avg the stable speed since last week ~350kbps & on certain HSDPA areas, users been getting 1200kbps using Sierra datacard..
But b4 u go on wireless...check whether is it bcos of mobility or stable speed? Wireless (Even Maxis/Digi) will not gurantee stable speed. for stable speed >1300kbps go for streamyx.
