BNM Shroud v TKO on .22 Disco

I've looked at the forums I currently peruse and have not found a single post on this. Has anyone done a side by side comparison to see which is more effective? I have a TKO and it is effective, but it makes the gun pretty dang long. I've been green lighted by my half to get a multi-shot breech, but it's appealing to me to get a shorter/shrouded barrel with the kit. Is it worth the 90 bucks?
