From what I've got in plastic, which is a reasonable range from different manufacturers, I'd say that Conte are you're natural comparables, both in level of detail, and size, bulk etc.
You could mix others, but I think you'll notice the difference in size and detail.
I'm getting the CTS GIs shortly, so can't say if these work well with TSSD, although the 2 Garys should be able to offer an insight.
