Is LR6 $149 better than LR5? Is the 6 engine faster than the 5? I know 5 does not have the Lens Profile for my 70-300 II and Camera Profile for the 80D I'm planning to Purchase ( or maybe the 5D MKIV ). I do not like the subscription model so CC is out of the question. B&H has the DVD version that I want to buy. Is there anything I should be aware of between LR6 and LR6? Is it pretty seamless going from 5 to 6?
