Well, I have both. As I have read it's pretty similar to what Whoam1 said. Moon is inner and Sun is more outer.
For some reason I can't differentiate between the two in myself. Probably because of either my age or due to having both aspects and thus can't recognize each of them; they both also aspect Saturn and other planets so they're 'molded' somewhat.
I'm a Virgo moon im a messy person and I try not to be insecure and judgemental. Pluto I find can either reverse or intensify a planets ability. (This may just be due to the fact my Sun/Moon=AC the midpoint being in Scorpio that I act differently than my sun moon and rising signs).
I have Sun trine Scorpio in Pluto 3rd house. My Pluto also has aspects to Mercury, Mars, Saturn, Uranus, and Neptune. I don't know how it differs from Moon aspects to Pluto, tbh, but despite the fact I have no other Scorpio in my chart, I greatly relate to being a phoenix, destroying myself to rebuild myself. I'm constantly searching for ways to propel myself forward and transform to the point I've made it into a little philosophy of sorts. I make a point of it to face the darkest aspects of myself and humanity and to dig as deep as I can into the depths to discover all I can. I'm very emotional, but at the same time I don't let things get me down. I like to learn all I can from everything that happens to me and I crave experience, both good and bad. Sometimes I even crave the bad more. I have a part of me greatly obsessed with destruction and death, but at the core, it's always to find some kind of grand truth of myself and of life. If I'm at a bad place in life, it'll be more egooritented, more about just plain old death itself, so there's no regenerative power, it's just dark. If I'm at a better place in life, it'll be more about trying to find the good in life as I believe death is the key to life, ultimately. I'll also have more of a focus on wanting to offer something to others, but I think that's just me
My only harsh Pluto aspect is Pluto square Saturn lol. But I know that's a generational aspect. I also have Pluto square my Chiron, but just speaking of planets here...I've been thinking a lot about self destruction lately. I often feel, and idk if I'm right or wrong, that I'm more self destructive than most people. I don't know if it's always a good thing, that's why I wonder about it because you're right. I don't fight it so much which is partially bc I feel it's futile to fight our emotions anyway. I struggle deeply with selfdestructive tendencies physically, emotionally, and mentally. But then bc of my selfdestructiveness, I've definitely gained some personal insight into creation. They're two sides of the same coin and both are transformative in their own ways...Where we have selfdestructive power, we have creative power. It just takes seizing that power to turn it around. Maybe that is harder if you have the hard aspects, but it's still in your power to do it If you look at it that way, this all or nothing Plutonic power, even if you're in the 'nothing' place or in the 'all bad' place, gives an opportunity where there wouldn't be one if that energy existed somewhere in the middle. If that makes sense. I hope it does. That's why I don't see our darkness or our demons as something negative to be avoided. Quite the opposite. As hard as it can be, we do eventually have to face these things so as to seize our powerInteresting to see how a "soft" aspect here works. You don't fight against Pluto's destructive tendencies, or rather, they don't rule you; you just incorporate that energy into your arsenal and use it to understand yourself. Pluto's a tool of empowerment for you. Kudos! Unfortunately, I can't deal with Pluto (although sometimes I want to trade my Saturnine energy for Pluto's, honestly).
