Volt meter just doesn't tell the whole story. A lot depends on the battery. I've been using Optima's in my boat for years. When fully charged they are at 12.7-8 volts. When my Powersonic deep cycle gets down to 12.7 I'm at 91%!!! Normal for this battery is 13.4-5 volts at 100%. The ability to customize the charge profile with the Bogart stuff counts for a lot with me.
After a lot of homework and reading I don't think that MPPT is really that much better on a small 12 volt system. It seems this stuff comes into it's own when using 48v panels and such.
