WOFF2 File. Left with autohint and on right with no hint.

WOFF File. Left with autohint and right with no hint.
WOFF2 has some glyphs taller than others, but WOFF does not and all is aligned properly across weights. On the other hand WOFF2 seem to be stronger and more clean in appeal across weights than lighter WOFF.
What should i do to achieve the appeal of WOFF2, but alignment of WOFF.
Im a total newbie in hinting. I use Fontlab7 and site I used to test web fonts was webfonttest site.

Personally, I recommend not using font tools to export web font formats, but instead build the fonts and then wrap them as WOFF2 and, if needed, WOFF using external tools. That way, you are sure that what is going into the webfont wrappers is exactly compatible with the non-webfont versions.
