Rotel RA 1062 integrated vs RB 1050 & RC 1070 seps

Any thoughts on the better of these two options?

Should I expect a noticeable improvement in the separates option?

I noticed the 1062 integrated has A / B / A+B which for me would be a benefit. Any other benefits either way beyond upgradeability?

Any tips on minimizing the brightness of the sound while still sticking with these components - I have B&W 602 speakers
