Which speakers do I pick and are they close in quality

This is like asking "should I buy a Ferrari or a Bentley?"  And the answer is the same -- it depends.  What are your priorities and preferences in sound reproduction and speaker characteristics?  Until we -- and hopefully and more importantly, you -- have a clearer handle on these things you're not going to get any meaningful advice or recommendations here.  

+1 Harbeth for softer FM sound. Great mid range. 

You don't elaborate on how you came to narrow the choice down to these two.  Are you buying new or second-hand?  Are these two models that are available to you?  They seem so far away from each other in the spectrum of speakers that the pairing seems odd.  And while it irritates me when other people do this, I'll break my own rule and agree with @willemj  re. the SLH5+.

The Harbeths are just abouts superior in every way. The 30.1/.2 might be the star of the Harbeth lineup.

The only question is whether you would miss the lack of deep bass.

Based on your listening preferences and components, I'd suggest the Totems. They'll reproduce Marillion and Floyd, et al, without skimping.
