Mild razor = a razor requiring perfect control of angle or it will not shave
Aggressive razor= a razor shaving even if the angle is slightly wrong
Aggressive as well as mild razors will produce a close shave for even the most coarse beards. As an aggressive razor is having more blade exposure, it is easier to get the blade against the skin. With a mild razor you only get the blade against the skin if you hold the razor perfectly at the right angle for that particular razor. It is thus easier to use an aggressive razor.
Personally, I think your main problem is angle, which then leads to your second problem with pressure. If you use a milder razor you are maybe trying to compensate the wrong angle with pressure. You maybe expect to feel some blade and if you are holding it at a wrong angle, you maybe give enough of pressure that you begin to feel some blade. This is a quite common problem. Wrong angle combined with pressure will give the result you described.
With each razor one need to find the perfect angle. In razor reviews, people are often commenting on how easy it was to find the angle and some razors aid in finding the angle by having a flat side on the top cap. You can not take a razor and just randomly hold the handle, as you describe it, "halfway between the floor and parallel".
Many razors work well by "riding the cap", which means you move down the handle from parallel with the floor until you barely begin to notice the blade. Then some razors are working well by riding the safety bar or comb, which means you place the guard against the skin and the handle right down, and then you lift the handle until you barely begin to feel the blade. In both cases you should not force the blade against the skin with pressure, instead you should adjust the angle until the blade is touching your skin. If your skin is bulging under the razor, you have too much pressure.
While razors like R41 will shave with almost any angle, even this razor is working best at certain angles. The skill in finding the angle is benefiting for any razor.
