This WAS the best credit card on the market, but a few days ago they took away the 100k points offer and reduced it to 50k, which is the same as the CSP. Also, 1 UR point is actually worth more than 1.5c. it's worth 1.5c/pt in the UR portal, but you can transfer it to other partners where you can get even more than 1.5c/pt. The Points Guy pegs a UR point at 2.1c in their valuation. I think that's a little high. Personally I tend to convert it at 1.8c/pt on average. But if you do a lot of overseas travel and fly first class, there are ways to rape some of the UR transfer partners (I'm talking 10c/pt rape).
Also, the "travel credit" is very flexible. You can use it on hotels and airfare as you would expect, but you can also apply it to things like Uber, public transit, tolls (I'm pretty sure), rental cars, etc. Also, they will re-imburse you for the cost of TSA-pre or Global Entry, which is normally $99 (and is good for 5 years). So now all of a sudden your $450 annual fee is really a $50 annual fee after travel re-reimbursement and TSA-Pre/GE re-reimbursement. Unfortunately I had gotten the CSP less than 6 months before the CSR was rolled out. The CSR is quite a bit better than the CSP (and the CSP was already pretty amazing).
If you think you missed the CSR 100k point bonus, there's still a way to get it. It just requires a little more effort. While the offer is no longer available online, you can still get it by going to a physical Chase branch and applying in person. But do this soon if you're on the fence, because you can only do this for a couple more months and then it'll be 50k points across all platforms. Honestly, even at 50k points, the CSR is probably still the best card on the market for most people, but the difference between CSP and CSR is closer and will depend on how often you travel and dine out. Also, the CSP waives the $95 annual fee for the first year while CSR does not. But whatever you do, don't apply for the regular Chase Sapphire. It's garbage compared to Preferred and Reserve. Though I believe all Chase Sapphires tend to give high credit limits. I was approved for $17k on the spot. Pretty bonkers, since it was almost double my other two cards. You do need excellent credit, though.
The one thing I will knock is the "access to airport lounges" isn't really what it seems. You don't just get access to airport lounges. You get a basic membership to priority pass, which in my opinion is garbage. Even with a Priority Pass you still have to pay $27 to get in a lounge, and even then it's only select lounges that are part of the Priority Pass network. Not worth it, imo.
For any Amazon Prime members, Amazon has a new Visa out with 5% back on all Amazon purchases and no annual fee. Also 2% for restaurants, gas, drugstores, and 1% everywhere else. Pretty dang good deal if you use Amazon much.
It's an okay card, I certainly wouldn't say it's amazing. Unless you're a schmuck you can find a card that gets you an effective 2% back on everything. So essentially you're getting an extra 3% extra back on Amazon by using this card (assuming you don't already have a card like Chase Freedom that occasionally puts Amazon as a 5% back in their rotating quarterly category). So if you spend $2500/yr on Amazon (which is prob a lot more than most people) you're getting an extra $75/yr back. That's okay, but not amazing when you take into consideration there's cards on the market that have effective $1k+ sign-up bonuses. What would make this card amazing is if they gave you 5 UR points per dollar on Amazon purchases instead of 5% cash. Despite being a Chase branded card, they offer the points back in the form of Cash instead of through the UR portal, which is lame. Also, this is only valid if you have Amazon Prime. So there's no annual fee for the card, but if you don't already have Prime then really there's a $99/yr annual fee.
