Think you’ll want similar lumen output and a 2700k bulb so the first.

The 15W LED is 10x brighter and would look nasty at 5000k

You want to replace the incandescent bulb with a LED bulb that has the same equivalent wattage. When in doubt, look at the lumens. A 100W equivalent bulb will be way too bright.

I like these because they’re glass and they kind of look like the old style.

you want lower light than what it says. Lower the light, the less glare you get on the glass. I cut all my games down about 80% of what they should be. No need to have a super bright backglass in a house. less is better.
