Yeah! Because a company is more reliable and available and has a lot
more capital than one of your friends, but you don't want to put all
your eggs in one corporate basket.

Hm, well here are some measurements:

http://allmydata.org/tahoe-figleaf-graph/hanford.allmydata.com-tahoe_speedstats_delay.html

But probably you'll get a better idea by experimenting with it:

http://testgrid.allmydata.org:3567/uri/URI%3ADIR2%3Adjrdkfawoqihigoett4g6auz6a%3Ajx5mplfpwexnoqff7y5e4zjus4lidm76dcuarpct7cckorh2dpgq/

(Warning: that grid is populated by "whoever reads
http://allmydata.org and connects", so I can't vouch for its
performance.)
