Although I often run RPGs without miniatures, I find them useful for new players, games with children and - especially - for games with lots of players. The third category often comprises the first two, making miniatures and floorplans especially useful.
Last weekend, I ran two games - the first for first-time players (my colleagues) and the second for my kids and their friends. I used the same scenario: a dungeon-crawl with an intro stolen wholesale from Jack Vance's
The Eyes of the Overworld.
For the first game, we used the second edition of The Black Hack. I loved running this. The player-facing rolls keep everyone involved, and the system's nicely intuitive (basically, everything's a d20 attribute check). I was very impressed with how the new armour system works. The degradation of armour's much easier to track than in the first edition, and gives the players lots of risk/reward decisions to make.
The Whitehack game was a blast too. It remains my favoured version of D&D for campaigns, because it allows a bit more subtlety and because there's a little more parity between players and NPCs. While I love The Black Hacks' dice-burning system for armour, traditional armour class allows you to fiddle around with monsters a bit more. For example, in Whitehack, I occasionally confront the PCs with brass automata who have AC 10 but only a single hit point each. That makes them tricky opponents without being overwhelming, and involves no bookkeeping whatsoever. It might be hard to achieve the same in The Black Hack.
I did, however, import The Black Hack's usage dice into Whitehack. These are very useful for rations, ammunition and the like. They ensure that resource management and uncertainty remain core parts of the game.
For both weekend sessions, I used hand-drawn floorplans. These are my preferred option for miniature-based RPGs. They're quick to make, they afford much more design freedom than commercial tiles, and they're 'what you see is what you get': if I've drawn a troglodyte hide staked out on the floor of a room, then that's what's there when the PCs enter.
Drawing out the floorplans means that the 'master map' can be very sketchy. I started with a rough scrawl and then drew out a clearer fair copy once the floorplans were finished. The advantage of this approach is that all your effort is visible for the players (and the crudeness of the GM's map makes it almost unintelligible to players should they happen to glimpse it.
I add 3D terrain where I have it, but I draw it in quickly in case I forget or misplace the scenics:

In the second game, we had eight players. The party split up, with two tackling the lower entrance while the rest headed for the orc outpost above. The floorplans were a huge help here, as it was easy to coordinate the action and for the players to visualise (eventually) how the two parts of the complex connected.
Another advantage of floorplans is that they speed things up. It's easy to glance at the table at the end of each turn and work out how far unseen monsters attracted by noise or scent will advanced through the dungeon. And of course it's far faster than drawing out rooms and corridors on a mat as you go.
