If I might add MY 2 pennies worth ...
I have never played a Hammond, or any organ for that matter, so I cannot comment using first hand experience ...
But I will say this - I played for 1 year with a 'classic rock band' here in RI and we had a B3 player ... He had heavy duty piano legs (the top of the leg was about 4 x 4 )hinged on the sides to carry it (one guy under each leg) ... this was my first experience with a B3 and it blew me away ...
At the Newport Jazz Festival this year, there was more than one player using a NORD, including the KB player for Bobby McFerrin ... they sounded fantastic .... I could not tell if they were using a Leslie or not, and of course they are going through TOTL PA systems ... Joey D, however, played a B3 ...

My 'simple' answer to this 'debate, is that - putting aside portability, price, playing OMB gigs in NH, etc. - if you want the best REAL sound out of ANY instrument, you use THAT instrument and a player who knows how to accomplish that ... you do not use a sim or a clone ...
Arranger KBs have their place, but they will not REPLACE the REAL thing ...
JMHO

PS ... I was just looking back at this thread and realized I pretty much was paraphrasing what spalding said in an earlier post ...
