From my angle, the 5" Edge style is ideal for Limited competition and as it's indexing and comfort for HD, for me anyway, is not an issue, it is the ideal compromise as a weapon that can accommodate both SD and competition.
If you are not overly accustomed to 2011 style pistols, you will probably notice little difference in feel initially between the two models.
Most importantly, with dry and live fire practice, you will adapt to whatever you buy so consider go with what you would prefer from a feel and asthetics standpoint.
