If I'm going to be summoning with Evolve Spirit, I tend to go with Onryo. They cost only 1 wd more than a Gaki (essentially nothing) and they have much greater versatility. I don't tend to start with them very often, but I play a fair number of 25 ss games, and I tend to start with mostly materials on the table (Seishin, dog, merc, Datsue).
They're not fantastic, but they're a 5 point model (often for 2 pts and 2 wds) that has a melee attack, ranged attack, debuff, deterent (immediate revenge), and Haunt.
The trouble with Shikome is the extra Seishin they cost, and now that they don't get prey when summoned, I'm using them much less.
