I've heard both hype 4 and top; they sound very similar but the top sounded a bit crisper and clearer while having more impactful (or boomy) bass. I prefer the top, but I can def see people going for the hype 4. I always see people bring up price when comparing the two, which at msrp yeah hype 4 is the better deal but...I got my top for $440 new after tax on aliexpress during a sale, which puts it at the same price as hype 4 post tax in my area. The top goes on sale pretty often and at that point that argument no longer exists. I also use my iems when i play games on my nintendo switch and the extra bit of bass the top had made certain sound effects seem really great like the impact of a greatsword hitting something in monster hunter. That's also something that can be adjusted through tip rolling. Hope this helps.
Oh actually since you also mentioned the monarch mk3 I may as well give my impressions there, too. I recently got to A/B the monarch mk3 w/ my xenns mangird top thanks to a fellow head-fier. Pretty much same bass assessment as the hype 4, it's tighter but less intense/boomy than the top. The rest of the mk3, particularly the treble was fairly similar to the top but definitely sounded more refined. Bit more sparkly, airy. It's not a night and day improvement and depending on the song, there were times I even struggled to hear much of a difference. Is it $600 better? I dunno that's a question to ask your wallet haha. Ignoring the price aspect my enjoyment of all three would be Monarch Mk3 > Top > Hype 4
