I have both.
Vezel is a totally different vehicle than civic.
Test drive Vezel first because its not everyone's cup of tea. Vezel has stiff suspenion, hybrid drivetrain; its really fast but it isnt as smooth as toyota hybrid system as it gives a bit of jerk at low speed, Vezel is complex due to its DCT system so get Vezel only fresh import so that it doesn't require any work. On the flip side, Vezel is feature rich; 8 airbags, heated seats, Honda sensing, dual zone climate, auto dimming mirror etc and is really powerful and fun (due to DCT) and gives good fuel economy.
Civic X is a simple car that doesn't require any complexity. It has one of the best driving positions and handling but oriel lacks acceleration, fuel economy and features as compared to Vezel. Civic X also has poor build quality and durability (Steering rack and Ac issues).
Both have good resale; Vezel maybe known for its gearbox issues but still sells easily.
It really depends on what you want... if you really want fuel economy, power and features than vezel or else if you want zero meter peace of mind option, a sedan and care about handling than civic x.
