The one on the left is superior for a massive number of reasons.

Simple and easy to print, make copies of documents without becoming illegible, and other paperwork related reasons.

Easy to recognize at a glance. The one on the right is really hard to make out at a small size. Just a bland beige blob.

There is a reason most familiar logos are monochrome or only a few colors, and simplicity is one of them. The one on the right looks like overly bust clipart.

The one on the left is a couch inside a house with a lamp, all of which make sense together. The plants overlap the wall and there is a chandelier over the couch on the right one. Who puts a chandalier over a couch?

Ugh, I know it is obviously awful but I had to get it out.
