I have usually had better luck from tabs than caps. Now, Don't get me started on liquid orals. Forget about any type of accurate dosing with that stuff.

I usually chew my tabs up anyways

Lots of factors to consider. Is your pressed tab UGL using a solvent to create a humogeneous mixture. Using a solvent to create an evenly distributed homogeneous mixture is your surest way to get each tablet to their advertised dosage.
Is your UGL hand blending their batches without using a solvent? I've heard of guys using. Ninja, vitamix and even a 5gallon bucket and a concrete mixer on a hand drill. The difference is huge when it comes to the quality assurance of that pressed tab. 10mg of halo better be 10mg of halo. Try making Cheque drops if you're a small UGL without using a solvent. Ya fucking right. Who wants to do QC on that shit? Better be using a labmax and not doing the taste tester bullshit. You're also ingesting some lubricant and filler with each tablet and that stuff isn't exactly good for you. Larger brands and operations got this shit down to a science. They have the money and space to pull it off with efficiency.

With Caps you don't have to worry as much with desired dosage issues. Each cap has the desired dosage added along with the proprietary fillers like creatine or whey protein. Some folks can even add small doses of other healthy supps to be the filler. Point is it's easier to pull off and easier to get right for these newer smaller Srcs.

In the end it's the same as it ever was. Find a Src you can trust and stay put.

Doesnt matter, all depends on the raws used. Pressed tabs can be indicative of a more advanced operation, but fancy machines are only as good as the raws used (and ratios). The difference you feel is likely from different raws used, or how the particular source (manufacturer) doses their product
