ok, here goes:
Feel: Paulsons are the undisputed champ in this regard. The Tina Hybrids are about 95% of the way there. They are REALLY that good! The Milano/12 Stripes are not even close. They are not the absolute worst, but they are a LONG way from the best. The worst are the ABS slugged "dice" chips and I would put the Milano/12 Stripes a lot closer to "dice" chips on the spectrum of feel. Rating 1 = Worst possible and 10 = best possible: Paulson = 10, Hybrids = 9, Milano/12 Stripe = 2, Dice =1
Looks & Security: If you are a casino Paulsons can look just about any way you want and can have the ultimate in security, however we can't get all that without having a gaming license. You can buy Paulsons from a closed Casino/Card Room and replace the inlays and have a semi-custom chip, but we are limited in this way. The Tina Hybrids are about as good as it gets as for looks. You can have them just about any way you want them. Milano/12 Stripes you just get what they are and you have NO security at all as anyone can buy your exact chips for pennies and bring them into your game. Rating: Paulson for Casino = 10, Paulson for home game = 7, Hybrids = 10, Milano/12 Stripe = 4, Dice =1
How they Stack & wear:
Paulsons stack really well when new, but they do suffer from wear. Fortunately it takes a LOT of play to put much wear on them. When I say a lot I am talking about 24/7 use for years type of "A LOT" For home game use you are NEVER going to see this sort of wear. Hybrids or any type of Ceramics will wear poorly in a casino as the dye gets worn off the chip eventually. Again, this only takes place with 24/7 casino use and would never happen in a home game type of use. Hybrids stack like bricks and basically will never wear in a home game Milanos/12 Stripes are really slippery and difficult to stack which makes them much less enjoyable to use. Rating: Paulson for Casino = 7, Paulson for home game = 9, Hybrids = 10, Milano/12 Stripe = 2, Dice =1
Collectability:
High end poker chips are expensive just like anything that is collectible. Nice Paulson chips can easily be $5-$30/chip. The good news is that they will typically hold their value really well or even go up in value over time. Cheap chips will be difficult to sell for anything at all used. If you decide you no longer want your cheap chips, you should assume a 100% loss. Rating: Paulson for Casino = 10, Hybrids = 5, Milano/12 Stripe = 1, Dice =1
I am sure I am missing plenty, but the main point is that you are getting basically the best of all worlds with the Tina Hybrids. You get a high % of all of the best qualities of a Compression Molded High end Paulson for only a little more than the cheapest chips out there when those cheap chips exhibit almost none of the good qualities of High end chips.
You know what the extra expenses are because of you being in Australia so I will accept what you say at face value. Regardless of cost, the market for used poker chips in Australia is going to be limited and both of these two choices will likely result in close to 100% loss should you choose to sell. Milanos and 12 Stripes both basically suck and you will most likely want something different at some point. The Tina hybrids are actually really nice and will last a lifetime so there is that
