I guess I'll be the one "other" voice today.
I know there are a thousand features and plug-ins Wordpress offers that others don't, but for me, using Wordpress was like trying to operate a right-handed can opener with my left foot. I tried, I really did, for
six weeks and never got past an ugly, basic page. The Codex (like a user's manual) is organized in some way that I don't understand, either. The Wordpress community even tried to set me straight--very open, helpful folks--but alas, my lightbulb never came on. I guess I just don't have the Wordpress gene!
So, since I already had a personal blog on Blogger, I made a prof. one there, too. Hallelujah! I got the basics set up in 20 minutes flat, then spent another hour or two tweaking until I got the layout to look enough like my own site to satisfy me. Other than paying a coder a few small bucks to make a change I didn't know how to on my server (to make the blog URL display as a subdomain of my domain, which Blogger allows and even invites you to do), I've been able to do everything I needed with my Blogger blog on my own, quickly, and the way I want it done.
You'll find many comparison articles that say Blogger is bad because X, Y, and Z. Be aware that some of the reasons people cite are not entirely accurate, or they used to be true but no longer are. For example, by default a Blogger page displays a bar on top that lets a user click away from your blog to see a different random one. I agree it wouldn't be good for a business blog to invite people to browse elsewhere. However, removing that bar from your layout is not hard (I did it without any trouble, and I'm not all that tech-savvy), and it is NOT against Terms of Use to do so. That's just one example of a not-quite-accurate argument.
The primary argument against Blogger that IS true is that it's not hosted on your own server, so you don't have complete control. However, I can honestly say that bothers me not at all. I don't see Blogger (it's Google, after all) going belly-up anytime soon, so I think it's pretty safe on their much-backed-up, large capacity servers.
Long story short: Wordpress = good, if you "get it"; Blogger = good also!
