CZ is actually a very good airline. Not sure about VN, but I've heard some stories here and there.
As for FFPs, do note that all Asian SkyTeam FFPs (VN, CZ, KE and soon GA, CI and MU) have mileage expiry dates attached to their miles: KE miles expire after five years, CZ, CI and GA miles expire after 36 months, and VN miles expire after 24 months. No information on MU.
If you're aiming for a fast way to earn elite status, GA gives you Silver status after 10,000 qualifying miles, and Gold status for 30,000 miles. If you're in a higher tier and you don't reach the number of miles needed to stay in your tier (for example, Gold), then you will be downgraded to the tier immediately below. So non-qualifying Golds become Silvers, Platinums become Golds, etc.
