Sydney pro vs. free

the pro themes is rated to 72% vs the free theme is rated to 97%. There is one critical alert in the pro-theme:
Title : Title The tags can only contain a call to wp_title() . Use the wp_title filter to modify the output.

I also test the themes with the plugin theme check. Sydney free was fine and pro has several requirements.
Is this of importance?
Sydney free

Sydney Pro
