The Geno 2.0 test is useful if you want to know about your deep ancestry and if you want to see if you have any new Y-SNPs. The Geno 2.0 test has effectively replaced the old FTDNA deep clade test. You get over 12,000 Y-SNPs on the Geno chip.
The 23andMe test is of more interest if you're interested in the health aspects. It's not so good for the Y-SNPs. They've reduced the cost of their test so that they can increase the size of their database.
Agreed. Mostly.

Its probably a question of semantics, but at the rate that we are now finding new SNPs, that span the gap between surname times and ye olde ancient times, it is a bit of a misnomer to call it "Deep" ancestry anymore. We may be looking at being able to say that a person is related to one group of people from regions W within 500 yrs, another group from regions W,X within 1000 yrs, another group from W,X,Y within 1500, another from 2000, etc., within the next few years. Some subgroups uncovered by WTY and 1K Genomes can pretty much do this already.
