The LG B6E supports Dolby Vision, HDR10 and HLG, which covers more content formats. The Samsung lists only OLED HDR+. Dolby Vision titles from Netflix and Disney+ will look their best on the LG.

Which handles a bright room better?

The Samsung S90H has a Glare Free coating, which the LG B6E does not list. If your room has windows or overhead lights, the Samsung will cut reflections better.

How big is the Samsung S90H really?

The title says 55 inches, but the specs list an 83-inch screen and a 56.9-inch width. Confirm the size with the seller before you order, since the two figures cannot both be right.

Both are OLED panels with similar lifespans, and neither listing gives a rated hours figure. OLED brightness fades gradually over years of use. The LG's lower price means less money at risk if you upgrade sooner.
