You my friend are playing with our emotions. Euro then Chinese seems to be in the works.
In my opinion, I'd rather the PAF go for 18 Typhoon T3. I do think there's more value in interoperating with the F-16 fleet and creating an offensive air-to-air capability. Yes, it'd be at the cost of deep-strike, but we can compensate there by tailoring the JF-17s for SOW and ALCMs, and also by adding a lot more GLCM launchers (with longer-ranged Babur variants). Plus, the GCC is flying the Typhoon in force, so we have a nearby source for spare parts and, potentially, additional aircraft some years down the line.
The Typhoon T3 has a higher upfront cost, but the Consortium brought the maintenance end down to near F-16 levels. The Consortium is also more open to third-party weapons integration since that's literally what the Typhoon is a result of -- e.g., KEPD 350 and Storm Shadow are redundant, but because of multiple needs, they both work on it. So, Ra'ad and H2/H4 integration is a non-issue.
Finally, I can't see why Europe would deny giving T1s on very favourable terms if there's a T3 contract tied to it. So, there's an opportunity to add even more offensive air fighters (in addition to T3s and additional F-16s) via ex-Italian and ex-Spanish T1s. If we have $4.5 b in cash (either our own or from the GCC), then I'd much rather it go to the Europeans than the Russians.
I did a cost breakdown 2 years ago:
The following is a very rough set of estimations (from open source info) regarding the cost of acquiring and maintaining the Eurofighter Typhoon Tranche 3.
After some difficult snags through the development of the underwhelming Tranche 1, which included the absence of long-range strike capabilities and wildly high operating costs, the Eurofighter Consortium (BAE, Airbus DS, Airbus CASA and Leonardo) have been bringing matters down to earth.
In 2015, BAE announced that it had slashed the cost of manufacturing the Typhoon (i.e. late T2 and early T3) by 20%. In fact, it cost the British exchequer around $126 m to produce each new RAF Typhoon.
In 2016, BAE initiated the TyTAN (i.e. Typhoon Total Availability eNnterprise) 10-year support contract for RAF Typhoons. It is worth $3.04 billion, ostensibly for 107 Typhoon T2 and T3. That averages to about $2.84 m per year per fighter, which is quite low considering what we've been accustomed to hearing about the Typhoon.
Since these are specifically BAE's numbers, I assume these are the costs of the actual parts, and not the labour and fuel (which would come from the RAF).
It's still quite low though, but fear not, it was intended. The TyTAN program envisaged bringing the cost of supporting the Typhoon T2/T3 to the "equivalent of a F-16."
Based on the US State Dept. release regarding Pakistan's F-16 request, the all-in cost of acquisition and support for each F-16 is $87 m. If the flyaway cost of each F-16 is $40 m, then the support cost per fighter would be $4.7 m (10 years) to $9.4 m (5 years) per year.
If we looked at the Rafale, it will cost India $11.79 m a year for each Rafale for 5 years.
Let's say it costs $8 m a year to fly a Typhoon T3. Over a 10-year period that would be $80 m. Add that to the flyaway cost and you're looking at a contract of $205 m a fighter with a 10-year support contract.
Throw in weapons, such as the MBDA Meteor, IRIS-T, SCALP, etc, and the cost will probably climb to $230 million a fighter.
This in the ballpark of the Super Hornet, Silent Eagle and Rafale. The Gripen is much cheaper, touching a ceiling of $150 m all-inclusive.
I'd wager the Su-35's operating costs will probably be around $9-10 million per year. However, it has a much lower flyaway cost of $83 million per fighter. That said, your main concern wouldn't be in affording the planes up front, but in flying them 20 years down the line - it'd be costlier to fly than Western jets.
On the other hand, this should also drive home how much cheaper the JF-17 is than each of those alternatives. It cost a certain customer $560 m plus spare parts to buy 16 JF-17s! That is $35 million per jet. Even on a 5-year cycle, that is an insane bargain, especially since it costs like $45 m to buy and fly a turboprop Super Tucano!!

Finally, it'd have the bluster of 1965. The Typhoon T3s would be like the F-104s, and the F-16s like the F-86. The only difference is that this time the PAF has another 200+ JF-17s behind them to distribute sorties, ensure air power availability, and hammer ground targets at a much more frequent rate.
