Welcome to the forum.
Your question to estimating software largely is one of experience. Some / all of the companies out there start to use one software and get "stuck" to it as it's harder to switch to another when all of their assemblies and mod's don't transfer over. With regard to which is better? Newer, faster doesn't always equall better. I have used McCormicks 6000 & 8000 versions, then at another company before that, they used Acubid. All worked and it would be hard to determine who had any avantages over the rest. Pricing is probably close on these.
You get the same thing with Traser and the other commodity pricing services, as long as they represent what you will pay for the items, have the ability to adjust your pricing buy-outs and update on a regular basis, they should all work in conjunction with the estimating program you are considering, but you should check first.
