Can anybody comment on the pros and cons. Need to design 2 small MSE walls.

RE: CIP vs Modular Precast Wall Face for MSE Walls
the movement i've seen over the past couple years that i think is most appropriate is to make the wall design, construction and testing part of a single package so that all the liability falls with the designer to provide a product that works for the site. the owner often has their own geotechnical testing firm provide periodic secondary testing as comparison testing only and this testing is merely to help the owner sleep at night. in other words, the secondary testing not intended to be part of the formal testing for the wall certification by the designer. and if the wall designer specifies x testing at y frequency, then their package should play by the same rules and follow the same protocol.
cast-in-place doesn't have nearly the issues. drainage must be provided but not nearly to the extent of mse structures. once the foundation is prepared, you pour it and eventually backfill with compacted/tested material then move on. the biggest problem with these is that if the walls are tall (above the original ground surface) or if the underlying soils are highly compressible, differential settlement could be an issue and has to be designed for. but with a qualified geotech on board, this can be overcome but it will cost money. even with the additional costs, i've seen some architects/engineers require cast in place due to the massive headaches often involved with mse walls/slopes. for small to moderate sized walls, i like concrete. for massive walls or crossing swales where settlement will be issues, i like mse structures (assuming the above mentioned items can be resolved by all parties).
good luck.
