Doesn't work that way. If you have LOS and range to target, so does your opponent. Being front-mounted, that generally also means your target is at an angle it can shoot back just fine.

More firepower, longer range, most likely more effective armor (Depleted uranium vs. iron), faster than most of the heavies and assaults.
Nope. Battlemech armor is what's known as BAR 10- that is, it won't through-armor crit under most normal situations. It has nothing to do with iron plate, being a metallic composite weave over a layer of ceramic and beneath it, the myomer and internal structure that supports and acts as a shock absorber/cooling mechanism to transfer even more energy safely across the unit. (Armored vehicles don't have as robust an underpinning, leading to more chances of critical damage-especially around delicate bits like tracks and hoverfans- and the more open structure lets non-energy weapons cool without heat sinkage, but also makes most vehicles horribly vulnerable to plasma/napalm style attacks)
20th century armor is BAR 5-7, which means anything dealing more damage than that BAR number threatens a crit even if it hits an armor facing. In the era just before primitive-tech BAR 10 armor, the most dangerous thing on the battlefield was a tank- with a large laser on it. And that predates things like PPCs or Gauss rifles. They literally had to rethink the concept of armoring units in a higher-energy battlefield, and the ablative armor that defeats a limited number of hits (but manages to distribute that energy remarkably well until total armor failure on a facing) was that solution.
The modern tank also uses what's known a "rifle" in Battletech terms, which actually does reduced damage to Battlemech armor on top of everything else, although any medium-heavy tank gun would inflict noticeable damage (but generally take multiple hits to penetrate more than the lightest protection). On top of that, Battletech ranges are actually missing a few zeroes or more simply so you can actually have a map small enough to play on, and a more realistic version would be pew pew pewing back at our modern armies without a worry with SRMs that actually have ranges more like 2700m, rather than 270.
Annnnnnyway, I'd rather be shooting at
Demolishers. Because dual AC/20 tanks hiding in low cover are scary.
