Beware of the stock footprints in any PCB program. They are often close to, or equal to the manufacturers recommendations which are optimized for machine insertion and wave soldering for leaded parts and pick and place with solder paste for SMD assembly. Neither of these are best for hand soldering by less than perfect DIY builders (rookies or old shaky hands like mine).

For many parts especially TO92's, but even for leaded resistors, I spread the leads and use larger pads.

In total agreement here.

That's why I like EspressPCB, I design all my own footprints with larger pads, typically 80 thou with 35 thou drill.

The only let down is that it's limited to round or square pads and no option for oval DIL style pads.

General rule I have:
If you want to make more than one of some PCB design, go computer, otherwise anything goes.
Although I've never done this, I've wanted to try a three dimension sculpture using discrete through hole components, no wire, just interconnecting leads. Pot it in clear liquid resin. The end result would look chaotic which most people assume is what electronics is about anyway.

The advantage of a well planned and thought PCB layout using a computer should be that of neatness and ease of identifying the various circuit elements. I am after that, and I also consider neatness as a plus. One simply cannot demonstrate the interior of an DIY amplifier if this is chaotically built. I want something worthy of admiration, and that, I am afraid requires great patience and perseverance.
