If you like the color rendition of halogens, the 3000K CRI90 spots from Osram are a nice match. IMO it's better to focus on quality: no flicker first, then higher color rendering bulbs which have a bit lower efficacy, but they are absolutely worth the extra watt. But if you upgrade that 100lm/W 8W LED to a 200lm/W 4W one, you only save 4 watts. If you upgrade a bulb from a 13lm/W 60W incandescent to a 100lm/W 8W LED, both output about 800 lumen, and you save 52 Watts, and it does add up. Note luminous efficacy of LED lightbulbs is not relevant unless you have a very large number of them. Now you may ask, why is the efficacy in lumen/Watt not what is printed on the box instead of useless 'ABC' ratings? Well, it's brought to you by the same bureaucrats that give my gas-guzzling V6 a better pollution rating than my high mpg diesel, lol. So you can look at how many lumens it outputs, look at the power, divide, and you get the efficacy in lumen/W.

The useful thing about this regulation is they made it mandatory to specify the light output in lumens.
