single speed conversion ratio question

Hi,
Have triple chainring set up with 170 cranks and 8 speed cassette on the back.
For the last year I have been using only outer chainring (52t) and 19t cog on back.
Going to switch to single speed setup.
Plan on getting Shimano Alfine front (with 170 cranks) and gusset conversion (16t and 18t) for the back.
Will my current setup of 52:19 (= 2.74) feel more or less the same as 45:16 (= 2.814)?
Thanks

It seems a very basic and straight forward question but I just want to make sure I'm not missing some other factor before I start buying stuff. Particular chain ring set up comes in 39,42 and 45
