I'd much prefer the VCO from the ASM-1. It is very reliable, easy to build and doesn't require a power consuming chip heater. This is important if you are going to build a larger number of VCOs. Also it is much easier to trim as it doesn't have (or need) a separate high range trimmer.
I have built the Doepfer PMS quad VCO, which is rather similar to the ones Tomg has on his site. It uses CA3086s for heaters and expo converters. I'm not quite satisfied with it and I'm thinking of replacing it with ASM-1 VCOs. I just need to cram four of them onto a 160x100 mm PCB.
