it will help to consider how you’ll be using it 90% of the time.
if it will go in your boat and never leave, consider getting something that is close to the height of your deck and can handle people standing on it. i’ve had both a built-in Just Encase and height-matched Lakewoods and it’s nice to have it double as useful casting deck surface rather than just taking up room in your cockpit. you do have to pay more for the strength in those products over the Plano-style plastic.
and if you’re going to take stuff in and out of your boat very often, consider getting more, smaller boxes. both Reck-n-Rack and Lakewood offer appealing options for this approach. the Plano in a duffel approach is both inexpensive and very portable.
my current set-up involves 2 Lakewood Pike/Salt boxes (same size as the Monster just a few inches less tall) that i use for casting baits. i have another 2 Lakewood Extreme boxes (Thorne Bros exclusive) that i use for my big trolling baits. i only bring what i need, and if it’s panfish or walleye time they’re out of the boat entirely.
another tacklebox “rule” that’s made my fishing life better: i don’t allow myself to own more lures than what i can – easily – fit in those boxes. i need to be able to get lures out and put back without a hook-knot mess. when i buy some new stuff, it’s time to sell some lures i haven’t been using to make room.
