Almost every single champion in that feature will add a lot of value to your roster, you should go for the feature.
There's an argument to maximise the number of 6* champs you have and going for basics, but I think quality is much better than quantity. The vast majority of everyone's 6* champs stay at R1 permanently anyway, so why do that when you have a >50% chance of pulling a 6* you can R2?
If you're interested in doing some math, there is a probabilistic way to determine which crystal is better for you (on average):
First go through both the featured pool and the basic pool and count the number of champions in each pool you would be happy to pull. And then calculate that as a fraction of each pool:
F= (# of champions in the feature pool you want to pull)/24 B= (# of champions in the basic pool you want to pull)/152
Next calculate the chance of pulling one of those heroes in 30k 6*shards (e.g. 2 pulls of feature vs 3 pulls of Basics):
The one with the higher success chance will (on average) be the better crystal for you .
*Note* One thing this analysis doesn't do is differentiate between different tiers of champions. (I.e. if you place more weight on pulling specific champions over others). To determine that you'd have to repeat this analysis and adjusting what champions you'd be happy to pull in each pool. E.g. repeat this with just Beyond God Tier champions in both pools, or Demi-God tier and up in both pools, etc.

Feature Success chance = 1 - (1-F)^2
Basic Success chance = 1 - (1-B)^3
The one with the higher success chance will (on average) be the better crystal for you .
