My Citrus ichangensis IVIA does not have juice pearls/caviar like finger limes. However, the pulp is kind of mushy. One can scoop it out with a spoon very easily. My N1Tri is very similar in this respect.
The smaller fruits are often seedless while the bigger ones are riddled with seeds. I have counted up to 40 seeds in one fruit. The pulp/juice is just sour, I don't notice bitterness. However, my taste buds aren't great. Maybe there is a slight bitterness, I wouldn't know.
The peel, however, has a horrible aftertaste, much worse than anything I have ever tasted. The first few seconds, it is not there and then it hits the back of your palate. I am very bad at describing flavours. It kind of tastes like kerosene mixed with soap and lingers for quite a long time.
