Vertical directivity and phase/GD will definitely be different. Most likely LR2 version has a bit higher distortion at some frequencies too. Optimal Fc is often higher for LR2
For a diyer subjectively best sound is more important than optimal measurements/settings! On-axis response don't have to be straight, PIR is closer to subjective "flat/smooth". I tend to prefer LR2 subjectively despite LR4 often measures a bit better, in my projects.
