depending what look you search, between gundam kits have lots of types. For start you can look between hguc line (the one in my badge is an hguc), easy kits but with good details and mobility. About weathering , damages etc you ca use easily your armor building skill with ground service gundams.
take a look at my one year war GB, between first 3 or 4 pages smeagoal and others made a brief explain of gundams standard line kits, also between the group have the dupes wip on a gundam battle tank in 1/35
