Do you mean the more addresses the chips are, the more anonymous they are？
In general: yes! Having more potential matches makes it less likely to find the one you're looking for.
I hate something,
Why not use the generic model and allow people to switch to the chips they like
2048 m BTC: change to 2btc
4096 m BTC: change to 4 BTCs
8192 m BTC: change to 8 BTCs
You can go a step further: 10 BTC sounds better than 8 too! But it doesn't fit the "split" and "merge" options.
