Apart from the speed difference of ram (133 vs 144 mhz) what are the differnces between the 2 models?

Id choose the smaller size of the wroom over the wrover but not at the cost of loosing some memory. The documentation doesn't really make it totally clear so any insight is very welcome

In general, the Wrover modules have PSRAM (in this case, 8MiB of it) that the Wroom does not. It essentially allows your programs to use 4MiB of RAM more, and another 4MiB you can use with bankswitching; with the Wroom you'd only have the 500'ish K of internal memory.

You may want to look at the modules and boards page in the docs for differences in general.
