At quick glance did not see a response to your Cbiz vs. others. I'm a solo practitioner and had Cbiz for years. I loved it and the guys are super. The only reason I changed is because I travel to out of the way places and internet can be spotty. If you are stationery it should work fine for you. I am on Sendouts now and love it but is is pricier. For the price you can't beat Cbiz. Anything else in this area feel free to reach out to me.
