Here's my honest opinion:
First of all, all cigars that I posted above tastes awesome, yet I forgot the taste of Montecristo No.2, so I will try again tomorrow.
Both Siglo II and Robusto obviously have signiture aroma of Cohiba, which is spicy at beginning then get deeper into both woody & sweety. Siglo II has lighter taste compared to Robusto, but in similar manner.
The custom picked Siglo II is better made than the regular. You can notice by looking at the appearance, and burns more beautifully and more equally all around.
Connoisseur A is extremely lighter compared to both Siglo II & Robusto, and very creamy. However, this creamy taste made me get tired at the end, and do not recommend to have any food or drink with it. Maybe just happened to me; i felt disturb in my stomach when I try cake & coffee with this one.
Another thing: I looked up some YouTube videos about finding fake cigars, and many uploaders would use barcode on the box or the seal on the cigar to distinguish either fake or real. However, custom ordered, which isn't for sale, sometimes lack seal, and doesn't come with barcodes unless buyer willing to receive them for sales.
