Evaluation

The Mouse DeathBot always outdoes the NVMRC Forcefield Trap in power (sometimes by quite a significant amount), but the NVMRC Forcefield Trap has a much higher luck total. So which is better, power or luck?

Luck allows the hunter to capture a mouse, regardless of difficulty. Very strong, physical mice like the Mobster Mouse are really only caught through luck, and without luck, a hunter can't catch them. However, luck is not reliable -- it doesn't always work and doesn't work anywhere near as often as power does. Power is the more faithful way to catch mice, but it cannot catch all mice.

Additionally, the DeathBot can be transformed into the PartyBot if one receives a Party Hat as a Birthday Gift or buys a party hat from Ronza's Traveling Shoppe. The PartyBot has higher luck and power ratings than either the ordinary DeathBot or the NVMRC Forcefield Trap, and the latter cannot be enhanced through crafting at the present time.

Historically speaking, most people picked the NVMRC Forcefield Trap because, given the environment of the Laboratory where it becomes practical for most hunters, the power is sufficient, while the extra luck helps to catch the Monster Mouse (though it becomes significantly easier to catch the Monster later in the Catacombs with more powerful traps such as the ACRONYM) among others. On the other hand, recent developments such as the availability of party hats and the utility of Stale Cheese have changed the calculations.

In the end, it comes down to preference and the likelihood of obtaining a party hat. It is generally not worth buying both traps since many mice beyond the Lab have different power types, making all physical traps "less effective" in the hunter's future.
