I disagree. I think they have some good modern elements and could be made quite nice with a recladding and podium renovation. It has a good urban feel IMO, only needs some updates. It's also a good vantage point for taking pictures of KiWi Condos and 154 Main East construction.

As for the building I dislike the most, I was originally going to say
the Fontainebleu. However on further thought, I think this one could probably be nice again with some exterior repairs done well.
My pick would be
