I'm definitely a convert. The boxes on the Reith logo seem to look more disfigured when smaller as the letters are right near the edge of each box. Because of the spacing on the new one, the boxes seem more separated when smaller and not just the slightest pixel of a line like on the Reith one. 

The C on the Reith logo seems "off" on the old one compared to now also.

I think you've got them a bit mixed up... 🙂

The new logo -- the one with the more generous spacing around the letters and between the boxes -- is the Reith logo (because it uses the new(ish) BBC Reith Sans typeface). 

The old logo -- the one with the letters "right near the edge of the box" and with the "slightest pixel of a line" between the boxes used a customised version of the Gill Sans typeface.
