Well Heineken is a Pale Lager and Urquell is a Bohemian Pilsner. You said you've been brewing "pale ale". I'm not sure if you meant it literally or not, but if so, it's a different style all together. Both are lagers as opposed to ales so you're going to get a very different flavor profile. Bo Pils and Pale Lager are going to be light and crisp. A good pale ale can be crisp as well, but the ale yeast is going to give a fruitier profile and the different grains of course will provide a different flavor. I'm not a big lager brewer, but my guess is that both pale lagers and Bo Pils will likely rely on Pilsner malts to a great degree whereas most ales have 2-row as a base. Again, different base malts, different yeasts, different flavors. If you're looking for more crispness out of your ales though, look to attenuate higher. If you're doing AG, then mash lower for a more fermentable wort which should drive the FG down which will produce a drier, crisper flavor.
