I would recommend trying before buying, hopefully you’ll have an RFD locally who has a stock of the various mods and will let you try them on your rifle.
Take your sticks, try each mod and see how they each affect the balance etc and it’ll give you a better idea of what to go for.
I bought my first moderator (Third Eye Spartan) for my Tikka .243 without seeing it. The spec looked good, I wanted an overbarrel so not to add too much length & it had a reasonably quoted weight.
I was then in the market for a mod for my Tikka .270 and this time decided to try before buying.
Took rifle to RFD and tried loads, off sticks, freehand etc and went for the .30 Cal ASE Jet-Z Compact. It wouldn’t have been on my shortlist as I didn’t want an “end can” and it was quoted as being heavier.
However, after trying it on the rifle, there was no noticeable different in weight or balance and it is a lovely compact mod, smaller diameter and doesn’t add much extra length to the barrel.
In the field, the Jet Z wins hands down, very effective on the .270.
The weight is not an issue for me & that’s it coupled with a 12-25 three draw Harris bipod. When coupled with a Z-Aim harness I can secure the rifle and walk all day with it no probs without it feeling unduly heavy.
I have now ordered a Jet Z for my .243 (in .25 Cal) and the Third Eye Spartan has been moved on.
I noticed the Spartan wasn’t as effective to the ear with sound suppression compared to quite a few different mods (friends use T8’s, T4’s and Northstars) and others have also commented on the effectiveness. This was an issue for me as our foxing duties are sometime on the “urban fringe” where the less disturbance the better so I wanted a change.
Don’t get me wrong, the Spartan is a really well engineered mod which ticked most of the boxes but in the end, the Jet Z performance in the field has won the day.
You’ll get loads of recommendations and I researched through the forum for a while but in the end I’m glad I get the Jet Z. Certainly at the top end of cost but worth it IMHO
Try before you buy would be my suggestion as it's a bugger deciding!!
